[HACKERS] Beta 6 Regression results on Redat 7.0.
Ok, thanks to our snowstorm :-0 I have been working on the beta 6 RPM situation on my _slow_ notebook today (power outages for ten minutes at a time happening at hour or so intervals due to 45mph+ winds and a foot of snow). Well, I have preliminary RPM's built -- just need to work on the contrib tree situation. I ran regression the usual RPM way (which I am fully aware is not the normally approved method, but it _would_ be the method any RPM beta testers would use), and got a different failure, one that is not locale related (LC_ALL=C both for the initdb and the postmaster startup in the newest initscript). See attached regression.diffs for details of the temptest failure I experienced. Regression run with CWD=/usr/share/test/regress, user=postgres. ./pg_regress --schedule=parallel_schedule This is the only regression test failure I have found thus far. I have never seen this failure before, so I'm not sure where to proceed. Now to attack the contrib tree (looking forward to my new notebook, as this old P133 takes an hour and twenty minutes to slog through a full build).

Re: [HACKERS] Performance monitor signal handler
I have talked to Jan over the phone, and he has convinced me that UDP is the proper way to communicate stats to the collector, rather than my shared memory idea. The advantages of his UDP approach is that the collector can sleep on the UDP socket rather than having the collector poll the shared memory area. It also has the auto-discard option. He will make logging configurable on a per-database level, so it can be turned off when not in use. He has a trial UDP implementation that he will post soon. Also, I asked him to try DGRAM Unix-domain sockets for performance reasons. My Steven's book says it they should be supported. He can put the socket file in /data. I figured it could just wake up every few seconds and check. It will remember the loop counter and current pointer, and read any new information. I was thinking of a 20k buffer, which could cover about 4k events. Here I wonder what your EVENT is. With an Oid as identifier and a 1 byte (even if it'd be anoter 32-bit value), how many messages do you want to generate to get these statistics: - Number of sequential scans done per table. - Number of tuples returned via sequential scans per table. - Number of buffer cache lookups done through sequential scans per table. - Number of buffer cache hits for sequential scans per table. - Number of tuples inserted per table. - Number of tuples updated per table. - Number of tuples deleted per table. - Number of index scans done per index. - Number of index tuples returned per index. - Number of buffer cache lookups done due to scans per index. - Number of buffer cache hits per index. - Number of valid heap tuples returned via index scan per index. - Number of buffer cache lookups done for heap fetches via index scan per index. - Number of buffer cache hits for heap fetches via index scan per index. - Number of buffer cache lookups not accountable for any of the above. - Number of buffer cache hits not accountable for any of the above. What I see is that there's a difference in what we two want to see in the statistics. You're talking about looking at the actual querystring and such. That's information useful for someone actually looking at a server, to see what a particular backend is doing. On my notebook a parallel regression test (containing 4,000 queries) passes by under 1:30, that's more than 40 queries per second. So that doesn't tell me much. What I'm after is to collect the above data over a week or so and then generate a report to identify the hot spots of the schema. Which tables/indices cause the most disk I/O, what's the average percentage of tuples returned in scans (not from the query, I mean from the single scan inside of the joins). That's the information I need to know where to look for possibly better qualifications, useless indices that aren't worth to maintain and the like. I was going to have the per-table stats insert a stat record every time it does a sequential scan, so it sould be [oid][sequential_scan_value] and allow the collector to gather that and aggregate it. I didn't think we wanted each backend to do the aggregation per oid. Seems expensive. Maybe we would need a count for things like "number of rows returned" so it would be [oid][stat_type][value]. -- Bruce Momjian| http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup.| Drexel Hill, Pennsylvania 19026 ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly -- Bruce Momjian| http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup.| Drexel Hill, Pennsylvania 19026 ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster

[HACKERS] RE: Re: More on elog and error codes
So we need some good error numbering scheme. Any ideas? I'm a newbie, but have been following dev and have a few comments and these are thoughts not criticisms: 1) I've seen a huge mixture of "how to implement" to support some desired feature without first knowing "all" of the features that are desired. Examination over all of the mailings reveals some but not all of possible features you may want to include. 2) Define what you want to have without worrying about how to do it. 3) Design something that can implement all of the features. 4) Reconsider design if there are performance issues. e.g. Features desired * system * subsystem * function * file, line, etc * severity * user-ability-to-recover * standards conformance - e.g.. SQL std * default msg statement * locale msg statement lookup mech, os dep or indep (careful here) * success/warning/failure * semantic taxonomy * syntactic taxonomy * forced to user, available to api, logging or not, tracing * concept of level * reports filtering on some attribute * interoperation with existing system reports e.g. syslog, event log,... * system environment snapshot option (e.g. resource low/empty may/should trigger a log of conn cnt, sys resource counts, load, etc) * non-mnemonic internal numbers (mnemonic only to obey stds and then only as a function call, not by implementation) * ease of use (i.e. pgsql-dev-hacker use) * ease of use (i.e. api development use) * ease of use (i.e. rolling into an existing system, e.g. during transition both may need to be in use.) * ease of use (i.e. looking through existing errors to find one that may "correctly" fit the situation, instead of creating yet-another-error-message.) * ease of use (i.e. maybe having each "sub-system" having its own "error domain" but using the same error mechanism) * distinction btwn error report, debug report, tracing report, etc * separate the concepts of - report creation - report delivery - report reception - report interpretation * what do other's do, other's as in os, db, middleware, etc along with their strong and weak points ... what else do you want... and lets flesh out the meaning of each of these. Then we can go on to a design... Sorry if this sounds like a lecture. With regards to mnemonic things - ugh - this is a database. I've worked with a LARGE electronics company that had 10 and 12 digit mnemonic part numbers. The mnemonic-ness begins to break down. (So you have a part number of an eprom, what is the part number when it is blown - still an eprom? how about including the version of the sw on the eprom? is it now an assembly? opps that tended to mean multiple parts attached together, humm still looks like an eprom?) They have gone through a huge transition to move away, as has the industry from mnemonic numbers to simply an id number. You look up the id number in a database :-) to find out what it is. So why not drop the mnemonic concept and apply a function to a blackbox dataitem to determine its attribute? But again first determine what attributes you want, which are mandatory, optional, system supplied (e.g. __LINE__ etc), is it for erroring, tracing, debugging, some combo; then the appropriate dataitem can be designed and functions defined. Functions (macros) for both the report creation, report distribution, report reception, and report interpretation. Some other email pointed out that there are different people doing different things. Each of these people-groups should identify what they need with regards to error, debug, tracing reports. Each may have some nuances that are not needed elsewhere, but the reporting system should be able to support them all. Ok, so I've got my flame suit on... but I am really trying to give an "outsiders" birdseye view of what I've been reading, hopefully which may be helpful. Best regards, .. Otto Otto Hirr OLAB Inc.

Re: [HACKERS] Fw: [vorbis-dev] ogg123: shared memory by mmap()
The patch below adds: - acinclude.m4: A new macro A_FUNC_SMMAP to check that sharing pages through mmap() works. This is taken from Joerg Schilling's star. - configure.in: A_FUNC_SMMAP - ogg123/buffer.c: If we have a working mmap(), use it to create a region of shared memory instead of using System V IPC. Works on BSD. Should also work on SVR4 and offspring (Solaris), and Linux. This is a really bad idea performance wise. Solaris has a special code path for SYSV shared memory that doesn't require tons of swap tracking structures per-page/per-process. FreeBSD also has this optimization (it's off by default, but should work since FreeBSD 4.2 via the sysctl kern.ipc.shm_use_phys=1) Both OS's use a trick of making the pages non-pageable, this allows signifigant savings in kernel space required for each attached process, as well as the use of large pages which reduce the amount of TLB faults your processes will incurr. That is interesting. BSDi has SysV shared memory as non-pagable, and I always thought of that as a bug. Seems you are saying that having it pagable has a significant performance penalty.

OK, seems there have been enough objections that I will not implement a "experts" page, nor change the way patches are applied. I will be posting a diff -c of any patches I have to munge into place, so people can see how stuff was merged into the code. It seems the problem of people having to massage patches after they are applied is either not a big deal, or the other ways of applying patches are considered worse.

It will also further disenfranchise the wider developer community. ISTM that the motivation is based on one or two isolated incidents where patches were applied when they should not have been. Tom's suggestion of insisting on CVS headers will deal with the specific case in point, at far lesser social and labour overhead. The last thing we want to do to people who contribute heavily to the project is say 'Gee, thanks. And you are now responsible for all approvals on this area of code', especially in late beta, when they are likely to be quite busy. Similarly, when we are outside the beta phase, we don't need the process. I suspect that anybody who has worked on a chunk of code in a release cycle will keep an eye on what is happening to the code. My suggestion for handling this process would be to allow an opt-in 'watch' to be placed on files/modules in CVS (CVS supports this, from memory). Then, eg, I can say 'send me info when someone makes a match to pg_dump'. Similarly, when I start working on a module, I can add myself to the list to be informed when someone changes it underneath me. This would be genuinely useful to me as a part-time developer. As a further development from this, it would be good to see a way for bug reports to be redirected to 'subsystems' (or something like that), which developers could opt into. So, using myself as an example, I would like special notification when a pg_dump bug is reported. Similarly, I might like to be notified when changes are made to the WAL code...

Additionally, the whole idea behind having error *codes* is that the client program can easily distinguish errors that it can handle specially. Thus the codes should be numeric or some other short, fixed scheme. In the backend they could be replaced by macros. This seems to be just an argument for constructing the value of PGERR_CACHELOOKUPFAIL carefully (which is what the VMS message source files did). The point is that when they are used by a developer, they are simple. #define PGERR_TYPE 1854 /* somewhere... */ elogc(ERROR, PGERR_TYPE, "type %s cannot be created because it already exists", ...) /* elsewhere... */ elogc(ERROR, PGERR_TYPE, "type %s used as argument %d of function %s doesn't exist", ...) I can appreciate that there may be cases where the same message is reused, but that is where parameter substitution comes in. In the specific example above, returning the same error code is not going to help the client. What if they want to handle "type %s used as argument %d of function %s doesn't exist" by creating the type, and silently ignore "type %s cannot be created because it already exists"? How do you handle "type %s can not be used as a function return type"? Is this PGERR_FUNC or PGERR_TYPE? If the motivation behind this is to alloy easy translation to SQL error codes, then I suggest we have an error definition file with explicit translation: Code SQL Text PGERR_TYPALREXI 02xxx "type %s cannot be created because it already exists" PGERR_FUNCNOTYPE 02xxx "type %s used as argument %d of function %s doesn't exist" and if we want a generic 'type does not exist', then: PGERR_NOSUCHTYPE 02xxx "type %s does not exist - %s" where the %s might contain 'it can't be used as a function argument'. the we just have elogc(ERROR, PGERR_TYPALEXI, ...) /* elsewhere... */ elogc(ERROR, PGERR_FUNCNOTYPE, ...) Creating central message files/objects has the added advantage of a much simpler locale support - they're just resource files, and they're NOT embedded throughout the code.

Hoo, that's interesting ... Exactly what fileset were you using again?
When you say 'fileset', I'm assuming you are referring to the --schedule
parameter -- I am invoking the following command:
./pg_regress --schedule=parallel_schedule
7.1beta6 distribution tarball. LC_ALL=C. Compiled on RedHat 7 as shipped.
I'm rerunning to see if it is intermittent. Second run -- no error. Running a
third time..no error. Now I'm confused. What would cause such an error,
Tom? I'm going to check on my desktop, once power gets more stable (and it
quits lightning -- yes, a snowstorm with lightning :-0 I certainly got what I
wanted.). So, more to come later.
Seeing that RC1 is in prep, is there a pressing need to upload and
release beta 6 RPM's, or will it be a day or two before RC1?
I think you might as well wait for RC1 as far as actually making RPMs
goes. But do you want to let anyone else check out the RPM build
process? For instance, I've been wondering what you did about the
which-set-of-headers-to-install issue.
Oh, ok. Spec file attached. All other files needed are the beta6 tarball and
the contents of the beta4-1 source rpm, with names changed to match the beta6
version number. There are some other changes I have to merge in --
particularly a set from Karl for the optional PL/Perl build, as well as others,
so this is a preliminary spec file.
But I was just getting the basic build done and tested.
To directly answer your question, I'm using 'make install-all-headers' and
stuffing it into the devel rpm in one piece at this time.

%description
PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including
transactions, subselects and user-defined types and functions). The
postgresql package includes the client programs and libraries that
you'll need to access a PostgreSQL DBMS server. These PostgreSQL
client programs are programs that directly manipulate the internal
structure of PostgreSQL databases on a PostgreSQL server. These client
programs can be located on the same machine with the PostgreSQL
server, or may be on a remote machine which accesses a PostgreSQL
server over a network connection. This package contains the client
libraries for C and C++, as well as command-line utilities for
managing PostgreSQL databases on a PostgreSQL server.
If you want to manipulate a PostgreSQL database on a remote PostgreSQL
server, you need this package. You also need to install this package
if you're installing the postgresql-server package.

Yikes. It gets weirder. Fixed the pg_inherits problem, went back to my Zoping, trying to optimize some views, and during another run, get an error that trelclasspq, one of my tables, couldn't open. Trying this out in psql, I get the same error message--the file doesn't exist. And, getting the oid for the file, looked in the directory--and this file is gone too! Now, I just made a good dump of the database, so I can always go back to that. But this seems to be a *serious* problem in the system. I have Zope 2.3.1b2 (most recent version of Zope) running on a Linux-Mandrake 7.2 box (server #1) It has a database adapter called ZPoPy, which is the Zope version of PoPy, a Python database adapter for PostgreSQL. PoPy is getting data from my PostgreSQL database, which is 7.1beta4, and served on a different Mandrake 7.2 box. Has anyone seen anything like this? I doubt the error is Zope *per se*, since Zope can only talk to the database adapter, and I doubt the database adapter has the intentional feature of delete-the-file-for-this-table in its protocol.

If someone else is running FlushRelationBuffers then it's possible for that routine to see a nonzero pin count when it looks. Further note: this bug does not arise in 7.0.* because in that code, BufferSync will only pin buffers that have been dirtied in the current transaction. This cannot affect a concurrent FlushRelationBuffers, which should be holding exclusive lock on the table it's flushing. Or can it? The above is safe enough for user tables, but on system tables we have a bad habit of releasing locks early. It seems possible that a VACUUM on a system table might see pins due to BufferSyncs running in concurrent transactions that have altered that system table. Perhaps this issue does explain some of the reports of FlushRelationBuffers failure that we've seen from the field. regards, tom lane ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

RE: [HACKERS] Beta 6 Regression results on Redat 7.0.
Further note: this bug does not arise in 7.0.* because in that code, BufferSync will only pin buffers that have been dirtied in the current transaction. This cannot affect a concurrent FlushRelationBuffers, which should be holding exclusive lock on the table it's flushing. Or can it? The above is safe enough for user tables, but on system tables we have a bad habit of releasing locks early. It seems possible that a VACUUM on a system table might see pins due to BufferSyncs running in concurrent transactions that have altered that system table. Perhaps this issue does explain some of the reports of FlushRelationBuffers failure that we've seen from the field. Another possible source of this problem (in 7.0.X) is BufferReplace..?

[HACKERS] Re: PostgreSQL JDBC Unicode Support
[Cced: to PostgreSQL hackers list] Alexander, I believe this problem was fixed in the latest JDBC driver, that is supposed to be shipped with 7.1. It asks your database which encoding is used for particular database while connecting to the database. So you should be able to see "select getdatabaseencoding" if you turn on a debugging option for postmaster. I also think the latest driver is compatible with 7.0.3, but I'm not sure.

I have a problem with our Postgres database, and intensive searches on the Internet/newsgroups didn't provide me with an answer. I was wondering if you would know the answer or point me towards it. In the nutshell, we are trying to get Postgres DB running that supports Unicode and interacts with clients via JDBC. We have PostgreSQL version 7.0.3 installed. I have downloaded the latest JDBC driver from http://jdbc.postgresql.org. I have created a Unicode database (confirmed through \l command in psql, reported encoding is 'UNICODE'). In that DB I've created a table with two fields integer and varchar(64). Then I store a record into this table. In my code I specify the string through Unicode escapes. After that I retrieve this value and write it out. I don't get my value back but rather ?. I'm attaching the code I use for reference. My Internet searches for the solution indicated that I need to apply some patches to JDBC driver. However, I don't know how to do that. Do you know where I may download the JDBC driver version with the appropriate patches applied? If you're using one, would you be kind enough and e-mail it to me. Also, having some experience with SQL Server, I know that if I wanted to store Unicode values into some column I was creating that column as nvarchar rather the varchar. Is anything like this required for Postgres? Your help is greatly appreciated. Thanks in advance, Alex Vaysman. ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster

[HACKERS] libpqeasy cursor error after multiple calls
Hi all,
I'm just wondering if this is an error on my part, or a bug. I have the
same trouble with PG 7.1beta6 and PG7.1 snapshot (March 8th) on Solaris
8 INTEL, Solaris 8 SPARC and Linux Mandrake 7.2.
When using the libpqeasy library in a C function, I have the following
section of code :
// Get the sequence number for the next directory entry (PostgreSQL
commands)
doquery("BEGIN WORK");
doquery("DECLARE c_getdirid BINARY CURSOR FOR SELECT
nextval('prescan_directories_idnum_seq'::text)");
doquery("FETCH ALL IN c_getdirid");
fetch(enumdirstruc_p-presentdirid);
doquery("CLOSE c_getdirid");
doquery("COMMIT WORK");
This is called once per entry in a filesystem (this is a filesystem
scanning utility) but after about 1000 or so calls, it errors out and
won't work again. I have to actually DROP the database and re-create it

[HACKERS] regression.diff wrong dir name
Hi all, Something minor, but when you do a "make check" from the main source directory and it finishes, it mentions that the regression.diff file is in ./regression.diff It's really at src/test/regress/regression.diff, and although not hard to figure out (it's a carry-over from pre 7.1), it might be confusing to people to new PostgreSQL.

Re: [HACKERS] pg_inherits: not found, but visible [IT GETS WORSE]
Joel Burton [EMAIL PROTECTED] writes: Yikes. It gets weirder. Fixed the pg_inherits problem, went back to my Zoping, trying to optimize some views, and during another run, get an error that trelclasspq, one of my tables, couldn't open. Trying this out in psql, I get the same error message--the file doesn't exist. And, getting the oid for the file, looked in the directory--and this file is gone too! This does not seem good. Just to clarify: in both cases, the pg_class row for the table is still there, but the underlying Unix file is gone? Barring major malfeasance from your kernel, it seems like Postgres must be issuing a delete on the wrong file when you are doing something else. This is particularly bizarre if you are just doing create/delete view, because in 7.1 a view hasn't got any associated file, and so no unlink() kernel call should be issued at all. I would recommend that you try to narrow down the events leading up to this --- in particular, keeping a postmaster log of queries issued (-d2) seems like a good idea. I doubt the error is Zope *per se*, Zope cannot be the culprit --- there is no API for deleting a table file without deleting its pg_class entry ;-). But it seems possible that some peculiar pattern of queries that they issue could be triggering a previously-unknown Postgres bug. I will be out of town all day tomorrow, but please see what data you can gather.

Re: [HACKERS] libpqeasy cursor error after multiple calls
I am kind of stumped. Glad to see _someone_ is using libpgeasy. :-)
I would be glad to run tests here if you can shoot over the code.
Hi all,
I'm just wondering if this is an error on my part, or a bug. I have the
same trouble with PG 7.1beta6 and PG7.1 snapshot (March 8th) on Solaris
8 INTEL, Solaris 8 SPARC and Linux Mandrake 7.2.
When using the libpqeasy library in a C function, I have the following
section of code :
// Get the sequence number for the next directory entry (PostgreSQL
commands)
doquery("BEGIN WORK");
doquery("DECLARE c_getdirid BINARY CURSOR FOR SELECT
nextval('prescan_directories_idnum_seq'::text)");
doquery("FETCH ALL IN c_getdirid");
fetch(enumdirstruc_p-presentdirid);
doquery("CLOSE c_getdirid");
doquery("COMMIT WORK");
This is called once per entry in a filesystem (this is a filesystem
scanning utility) but after about 1000 or so calls, it errors out and
won't work again. I have to actually DROP the database and re-create it
again before the code will work again at all. Just vacumming doesn't
help, nor does just shutting down the database and starting it again

Re: [HACKERS] Re: FAQ: Current state of replication ?
I found interesting paper http://citeseer.nj.nec.com/330257.html "Don't be lazy, be consistent: Postgres-R, A new way to implement Database Replication" Abstract: Database designers often point out that eager, update everywhere replication suffers from high deadlock rates, message overhead and poor response times. In this paper, we show that these limitations can be circumvented by using a combination of known and novel techniques. Moreover, we show how the proposed solution can be incorporated into a real database system. The paper discusses the new protocols and their implementation in PostgreSQL. It also provides experimental results proving that many of the dangers and limitations of replication can be avoided by using the appropriate techniques. 1 Introduction Existing replication protocols can be divided into eager and lazy Regards, Oleg On Tue, 20 Mar 2001, Thomas Lockhart wrote: What is the current state-of-the-art WRT replication of any sort ? If anyone has homebrew solutions that they can share, we would welcome tyring too. There is some code in contrib/rserv for 7.1 which does table replication. It has some restrictions, but does implement the basic concept. I think a tarball to do the same for 7.0 and earlier is available at www.pgsql.com (just Makefile differences). We are currently working through the issues involved with multi-slave replication and the ramifications for failover to (one of) the slaves. It looks like the rserv code may assume too much independence between slaves and replication sync information, and failover may be not-quite-right in those cases. Will be posting to the list when we know the answer (though contributions and inputs are of course always welcome!). afaict changes in rserv schema, if necessary, will not be available for 7.1, but we'll be posting patches and updating the CVS tree. btw, it looks like TODO.detail/replication predates the replication implementation, and has no real relationship with the implementation. There is some thought that WAL/BAR features can help support replication at a different level than is done now, but that is work for the future afaik. - Thomas ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED] Regards, Oleg _ Oleg Bartunov, sci.researcher, hostmaster of AstroNet, Sternberg Astronomical Institute, Moscow University (Russia) Internet: [EMAIL PROTECTED], http://www.sai.msu.su/~megera/ phone: +007(095)939-16-83, +007(095)939-23-83 ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html

I think we could just prefix the actual message with the error code, at least as a start. Since they're all fixed width the client could take them apart easily. I recall other RDBMS' (Oracle?) also having an error code before each message. -- Peter Eisentraut [EMAIL PROTECTED] http://yi.org/peter-e/ ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])

put varargs into parentheses to avoid need for ... macros see Tom's proposal
I'd be inclined to make it
PGELOG((ERROR, PGSQLSTATE_TYPE, "type %s cannot be created because it already exists",
...))
The extra parens are ugly and annoying in any case, but they seem
slightly less so if you just double the parens associated with the
PGELOG call. Takes less thought than adding a paren somewhere in the
middle of the call. IMHO anyway...

[HACKERS] Final Call: RC1 about to go out the door ...
Okay folks ...
We'd like to wrap up an RC1 and get this release happening this
year sometime :) Tom mentioned to me that he has no outstandings left on
his plate ... does anyone else have any *show stoppers* left that need to
be addressed, or can I package things up?
Speak now, or forever hold your piece (where forever is the time
between now and RC1 is packaged) ...

Re: [HACKERS] FAQ: Current state of replication ?
1. One "writer", many "reader" PostgreSQL servers. We will want to write provisioning / configuration information centrally and can tolerate a "writer" failuer for a time. 2. Consitency at the transaction level. All changes to the "writer" server will be wrapped in transactions, and there will be foreign key consistency checking in many tables. 3. Delays from "writer" through to consistent state on "readers" can be tolerated to within a few minutes or even more. All read-servers must be in the same state when answering requests. Our objective is to acheive performance and some fault tolerance as the data is going to be used for near-real time configuration of various other backend systems in an almost traditional 'net environment. As we are coding various other stuff for this project over the next few months, any help we can be in developing for this part of PostgreSQL, just let me know. While knowing very little about PostgreSQL internals, we learn quick. Peter, I've been mostly a lurker here (at least on the hackers list) for a couple of years, but I thought I would "de-lurk" for long enough to reply to your question ;) Attached is the source for a replication solution I recently wrote for a project I'm working on. I think it meets your criteria. I was considering sending it to the list as a possible contrib after 7.1 was released (if anyone is interested, and the code is worthy), but since you asked, here it is. A few disclaimers are in order. First, I am *not* an experienced C programmer. The code works in the limited testing I've done so far but needs to be reviewed and scrubbed by someone with more experience. Second, I have not yet used this in production, so use at your own risk. Third, I have only tested it under Red Hat 6.2 and 7.0. Finally, it will only work with = PostgreSQL 7.1 beta3. Basic installation instructions: copy pg_lnk.tgz to contrib under the PostgreSQL source tree tar -xzvf pg_lnk.tgz cd pg_lnk ./install.sh I'll be happy to answer any questions to help you get it installed and working. I would appreciate any feedback, improvements, general guidance if you decide to use it. Thanks, Joe lurking once again . . . pg_lnk.tgz ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
