[GENERAL] how can I create the DML for an existing database - within an application
I want to get the output frompg_dump --struct-only --table=whateverinside a programm. Of course I could call pg_dump in a seperate process and capture the output and all; but ...as PGAdmin is doing it someway, I strongly suspect there is a kind of call to recreate the DML language from a table in the database.

[GENERAL] Truncate and Foreign Key Constraint question
This is in postgres 8.1:
PostgreSQL 8.1.1 on x86_64-unknown-linux-gnu, compiled by GCC gcc (GCC) 3.4.2
20041017 (Red Hat 3.4.2-6.fc3)
I've got a table in one schema (work.client_collect_rates) which has an FK
constraint with a table, content.collections_l (definitions shown below).
There's about 500 entries currently in my collections_l table.
I need to wipe out the contents of the collections_l table nightly and refresh
it from a remote master source. (Don't ask ... long & sordid history)
As the sequence below shows, I dropped the FK constraint successfully, but when
I run TRUNCATE collections_l it says:
ERROR: cannot truncate a table referenced in a foreign key constraint
DETAIL: Table "client_collect_rates" references "collections_l" via foreign
key constraint "$2".
HINT: Truncate table "client_collect_rates" at the same time.
This truncation of the second table is *not* an option, but since the
constraint "$2" is clearly gone, I am wondering what in the name of sweet
apples is going on ? Is this a bug ? Have a developed premature senility ?
Any clues for the clueless would be gratefully accepted!

If I were you, I'd probably do that by creating a bunch of domains and using the domains instead of plain text/etc as the column types. See CREATE DOMAIN.

[GENERAL] Evaluating client processes vs stored procedures
List, I have a client process that is causing some performance issues with my app. On my current platform, the standard automated profiling tools are not available. Consequently, I can't easily determine where the bottleneck is in the process. I have an inkling that rewriting the client process to a stored procedure (implemented in C), will give at least a modest speed boost. What I'm trying to evaluate is the risk proposition of my effort. I really need a big bang for the buck, and I'm willing to risk a week of effort if the general consensus is that it's a good bet. I estimate a week to re-implement as a stored procedure, vs about 3 to manually profile what I need. Will I find out in 3 weeks what I already suspect? If I do profile it and fine-tune the slow points, would the newly architected client STILL run faster as a stored proc? So - any sage words of wisdom for those who've been down this path? I realize that w/o specifics no one can say for sure. General feelings from those with experience are welcome. Process specifics: Currently, the client process is run once a night. It's run on a separate machine than the database. Values in one table are updated by evaluating user defined functions against values in another table. Here's the pseudo-code: For each formula_row in formula_table: newValue = evaluate(formula_row.body) update formula_row set value = newValue where sid = formula_row.sid The evaluate function is a typical lexx/yacc parser. The formula body may refer to other formulas in the table, or to constant values in another table. If I do implement it as a stored proc, I'd likely add triggers so that the formulas would be re-evaluated once values in the constants table get updated. ---(end of broadcast)--- TIP 1: 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

When you say reliability, I'm not sure your definition is my definition. Is is that the database MUST be up during business hours, even if the updates that happen during the day can't go through? Or even if those updates get lost and have to be re-entered that's OK, as long as the data entered by the batch file at night is available for business processes. There are a lot of ways to set this up, and each tool in the tool box has its advantages and disadvantages. PITR, Slony Replication, pgpool, pgcluster, mammoth replicator, bizgress, bizgress MPP... I'd guess that the data entered during the day is the most important. If this is so, you could set up slony replication on those tables to a backup machine so that should the primary suffer catastrophic failure you still have the inputs.

In my experience the better SANs are a good way to go if you need flexibility or easy managment (especially if you need to do things besides database) without losing performance.

Lame, I know. Similarly, some people have invented RAID 50 = RAID 5+0.

I am curious because RAID 10 has come out since the last time I took a look at RAID technology. I am not sure what it actually does differently from RAID 5. This question of data security is becoming of increasing importance to me professionally since I will soon have to advise the company I'm working with regarding how best to secure the data managed by the applications I'm developing for them. I will need overall guidelines to produce a design that makes it virtually impossible for them to lose even on field in one record. The data is both sensitive and vital. Fortunately, I have a few months before we need to commit to anything. Also, fortunately, with one exception, the applications rely on a data feed that comes in once a day after normal working hours, so I won't have to worry about writes to the DB other than what my script does to load the datafeed into the DB. All other access is read only. This should make it easier to produce a strategy to protect the data from any kind of technology failure (software or hardware). Cost is a factor, but reliability is much much more important! Thanks, Ted ---(end of broadcast)--- TIP 4: Have you searched our list archives? http://archives.postgresql.org

I'm using metaphone() together with levenshtein() to search a place name
gazetteer database and order the results. That works reasonably well and
gives interesting results ("places with similar names"). However, it does
not cover "partial" matches (it does just compare the whole string, and does
not find multi-word names when just a single word is entered, eg. it would
not find "santa cruz" when you just enter "cruz").
Regarding db structure: I've specifically added a column which contains the
metaphone string (loaded with "UPDATE places set pname_metaphone =
metaphone(pname, 11)") - this row is obviously indexed (and, with functional
indices, actuall redundant ;). i'm then using "SELECT * from places where
pname_metaphone = metaphone('searchstring', 11)" to retrieve similar names.
levenshtein is used to order those rows by string distance.
try it at http://nona.net/features/map/
I haven't attemted yet to combine tsearch2 and metaphone results - that
would probably be the PerfectSolution(tm).
hope that helps

How much redundancy would you build in, and at what > granularity? There have been NUMEROUS discussions of RAID-5 versus RAID 1+0 in the perform group in the last year or two. Short version: RAID 5 is useful, with large numbers of drives, for OLAP type databases, where you're trying to get as much storage as possible from your drives. RAID 5 pretty much REQUIRES battery backed cache for decent write performance, and even then, will saturate faster than RAID 1+0. RAID-5 cannot survive multiple simultaneous drive failures. RAID 1+0 requires better than average controllers, since many serialize and lockstep data through the various layers of RAID on them. It provides less storage for a given number of drives. It is faster for OLTP workloads than RAID-5. RAID 1+0 can survive multiple drive failures as long as two drives in the same mirror set do not fail at once. With increasing number of drives, the chances of a RAID 5 failing go up linearly, while the chances of RAID 1+0 failing due to multiple drive failure stay the same. ---(end of broadcast)--- TIP 1: 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

Actually, after reading that page, I'm don't think DB2 came off as being much better than PostgreSQL. The postgres database is new to 8.1, I believe. I think it was as much as anything to stop the bothersome "database postgres does not exist" error messages a newbie would get when starting out. In addition to no mention of autovacuum, there's no mention of analyze. Sense this is a guide for people going FROM postgresql to db2, it's forgiveable I guess to leave out autovacuum, but analyze is really closer to the RUNSTATS command than is the vacuum command. vacuum analyze would probably be the best match. The one thing that bothered me is that they didn't mention the serializable transaction mode in postgresql. It's quite possible that people migrating from transaction systems utilizing serializable will run into more bumps in the road on db2 than folks migrating from a system that uses Read Committed. ---(end of broadcast)--- TIP 1: 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

[GENERAL] "Hidden" field for each column
Hi, Is there any way that I can consistently (across all tables) add a parameter defining "what" each column "is"? (sorry, crappy grammar and ill-formed question). I want to be able to embed in the database parameters that tell it how to interpret each column. In other words, while the TYPE for two columns might be text/char/varchar/etc., the data that each contained could have vastly different interpretations. For example, it might be a surname. Or, the name of a city. Or, the name of a handtool. Or a street address. I would like the support routines to be able to look at these parameters and adjust queries and other activities accordingly. So, when matching a surname, it might apply some heuristics built on metaphone. Yet, when matching a book's title, may try some simple substitutions and permutations (e.g., stripping words like "The" from the beginning of the title; or relaxing rules for punctuation or capitalization). Burying this information in the database itself will let the applications be unconcerned with adding this level of support at their level -- and afford all applications a consistent set of capabilities. On a similar, but different, note, are there any ways to "hide" a value behind each datum? I.e. to treat each entry as a struct containing the actual data type PLUS this "hidden" value? Without explicitly creating ADT's for each potential datatype? (sorry, I realize both questions are off-the-wall and I can undoubtedly come up with kludges to implement them but I was hoping for something "slicker"... :>) Thanks! --don ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster

Ok, i am not a raid expert. but in my understanding RAID 10 is faster than two RAID 1 arrays, aren't they? So, given that i can put up to 4 S-ATA disk in my server and the mentioned raid controller.
