If you just want to know what kind encodings are there in the database, why not use: SELECT DISTINCT ON (encoding) pg_encoding_to_char(encoding) AS encoding FROM pg_database; Also, FE's encoding could be any valid encoding that FE chooses, i.e. it' not BE's choice. Can you show me more concrete examples showing what you actually want to do? 3) Is there a way to query available encodings in PostgreSQL for display in pgAdmin. Could pgAdmin display multibyte chars in the first place ? Wao. If pgAdmin could not display multibyte chars, all discussions here are meaningless:- Apparently it can, I just don't know how to do it yet!

[HACKERS] pgAdmin users upgrading to PostgreSQL 7.2
Hi,
It's come to my attention that users of pgAdmin (the original, not pgAdmin
II) will not be able to dump/reload their 7.1.x databases into 7.2 without
an additional step in the upgrade procedure.
This is because pgAdmin creates a number of views on the server which
include the oid column from tables such as pg_attribute - obviously
attempting to reload these view will cause an error as there is no longer an
oid column in pg_attribute in 7.2.
pgAdmin II is unaffected by this problem.
I will obviously try to assist anyone who suffers from this problem, but if
the following text can be added to the INSTALL file and anywhere else that
may be appropriate it might help ease the pain!
{at the end of #2 under 'If you are upgrading)
pgAdmin 7.x users will need to drop server side objects before dumping
their database, otherwise the reload will fail. To do this, select
'Drop all pgAdmin Server Side Objects' from the 'Advanced' menu.
pgAdmin does not support PostgreSQL 7.2, instead, please try pgAdmin II
from http://pgadmin.postgresql.org/.
Regards, Dave.

[HACKERS] RFD: access to remore databases: altername suggestion
Hi!
0. I think access to other databases is really important. There was
a discussion about that. Using a dot operator to specify a
database (schema) seems to be very standard and elegant.
But there is another way to implement it. Here is my
suggestion.
1. First, some syntax:
CREATE [ SHARED ] [ TRUSTED ] CONNECTION conn_name
USING 'conn_string'
[ CONNECT ON { LOGIN | USE } ]
[ DISCONNECT ON { LOGOUT | COMMIT } ];
Description
Creates a connection definition (Oracle: database link) to
a remote database.
SHARED
Means only one instance of connection exists and is accessible
to all qualified users.
TRUSTED
Only superusers can use this connection (like TRUSTED modifier
in CREATE LANGUAGE).
conn_name
Just an identifier.
'conn_string'
Connect string in standard form accepted by libpq
'PQconnectdb' function.
CONNECT ON { LOGIN | USE }
Defines whether connection should be established when
user logs in, or when references remote object for the
first time (default).
DISCONNECT ON { LOGOUT | COMMIT }
Defines whether connection should be closed when
user logs out (default), or when transaction is ended (COMMIT,
ROLLBACK, but also exiting).
2. Additional commands
ALTER CONNECTION conn_name
USING 'conn_string'
[ CONNECT ON { LOGIN | USE } ]
[ DISCONNECT ON { LOGOUT | COMMIT } ];
Description
Changes behaviour of a defined connection (same parameters
as for CREATE CONNECTION).
DROP CONNECTION conn_name;
Description
Hmm... drop the connection definition?
Also a new privilege CONNECT should be added, so
GRANT CONNECT ON remote_database TO SCOTT;
can be processed.
3. How to use this?
SELECT local.id, remote.name
FROM orders local, emp@remote_database remote
WHERE local.emp_id = remote.id;
SELECT give_a_raise_proc@rempte_database(1000);
4. Some notes (in random order)
If a 'conn_string' does not contain a user/password information,
connection is performed using current user identity. But, for SHARED
connection always use a 'nobody' account (remeber to create
'nobody' user on remote database). For security reasons
'conn_string' must be stored in encrypted form.
When CONNECT ON LOGIN is used, connection is etablished
only if user has CONNECTprivilege granted on this. For TRUSTED
connection also superuser rights must be checked.
If first remote object is accessed within a transaction, a remote
transaction should be started. When trancaction ends, remote
transaction should also be ended same way (commit or rollback).
SHARED connection should be established when first user logs in
or uses remote object (depends on CONNECT ON clause) and
terminated when last user ends transaction or disconnects
(depens on DISCONNECT ON clause). Of course no remote
transaction can be performed for SHARED connection.
Of course it would require lot of work, but can be parted. The
minimum IMHO can be a SHARED connection with
CONNECT ON USE and DISCONNECT ON LOGOUT behaviour.
5. Conclusion
I know it is much easier to 'invent' a new functionality than
to implement it. I also realize this proposal is not complete
nor coherent. Still want to listen/read your opinions about it.
Regards,
Mariusz Czulada
P.S.: Is it planned to add 'auto_transaction' parameter on server
or database levels, so events like login, commit or rolback
automaticly start a new transaction without 'BEGIN WORK'
(like Oracle does)?

[HACKERS] timestamp and time now support precision
I've implemented timestamp and time precision per SQL99 spec. The syntax is TIMESTAMP(2) WITH TIME ZONE or TIME(0) etc etc. One result of this is that timestamp is no longer a valid external function name (among other things) due to parser ambiguity between TIMESTAMP(2) and, say, TIMESTAMP(date 'today') (the latter used to be supported). If you need to explicitly call a function by that name you need to surround the function name with double quotes, as in select timestamp(date 'today'); All regression tests pass, though we will probably need updates to the pre-1970 regression results. The CVS notes follow... - Thomas Implement precision support for timestamp and time, both with and without time zones. SQL99 spec requires a default of zero (round to seconds) which is set in gram.y as typmod is set in the parse tree. We *could* change to a default of either 6 (for internal compatibility with previous versions) or 2 (for external compatibility with previous versions). Evaluate entries in pg_proc wrt the iscachable attribute for timestamp and other date/time types. Try to recognize cases where side effects like the current time zone setting may have an effect on results to decide whether something is cachable or not. ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

Re: [HACKERS] RFD: access to remore databases: altername suggestion
You are attacking here two things:
a) schemas, which should be done in 7.3, thus multiple databases on same
host would be unnecessary.
b) connections to remote host' databases, which is partially implemented
already (in a ugly way, but...) see contrib/dblink
What you described is a syntactic sugar to implement b) which isn't a bad
idea, but just consider, it is already done. sorta.

[HACKERS] My last ECPG commit
Christof just told me that I overwrote Tom's patch fixing the setlocale problem in ecpg. I did not notice that and for some strange reason did not get Tom's mail either. Anyway, the CVS problem was that I use cvsup to keep an up-to-date source tree. I have set up my system so that it updates everytime I go on-line. I also automatically update my pgsql-ecpg checkout. This has a long history as I started using cvsup before I even was a developer and never felt the need to change that. When I change some stuff I usually do this in the complete source tree as I need it to even compile ecpg. Then I copy over the files I changed to the cvs checkout and commit them. This works well since it does not matter if the checkout is done via cvs or cvsup. But now cvsup on my system stopped working because of that 10mil seconds bug but I failed to notice. Hey, I don't check the logfiles everytime. So when I made my last commit, I simply used these old files as a base and removed Tom's patch. I guess I better switch to cvs. :-) Making this long story short, Tom, I can understand if you feel angry about this (and I'm sure I would) and I will try my best to never let it happen again.

Just a HUMOR, no offense and take it easy!! = If someone ask's you how do you compare the features and capability of these three popular SQL servers: Oracle, PostgreSQL and MySQL ?? Then comes the answer in layman's terms: "A Elephant, Powerful White Horse, Fast Hare (Rabbit). Please tell me which animal you want ??" Oracle = Elephant, Big and hefty but very bulky PostgreSQL = Powerful White Horse, top breed horse (I love riding horses) MySQL = Fast running Rabbit (Hare), I like rabbits as pets, very decent animals!! Oracle, PostgreSQL are in development for the last 22 years. Both had originations in University of California, Berkeley. Both are very mature, ACID compliant (Atomicity, Concurrency,.) and are robust. MySQL is like rabbit, it runs fast and can be a good pet. But see, the speed is NOT at all important when it comes to SQL server - it is the ACID compliance, Data Integrity and robustness and features and language interfaces which are important. You must not compare Elephant with Hare (Oracle with MySQL) But the best among these three animals is - White Powerful Horse!! (PostgreSQL !!) Why do you think every person is waiting in a long queue to get a ride on "White Powerful Horse" (PostgreSQL) ???

That way the select and the update can be assured that no one else is changing the data. THANK YOU! That's what I thought, but the documentation was a bit light on the subject of SELECT ...

So to mirror it back to you, if I do next_id_block ( count ) (1) read idfactory row FOR UPDATE (2) update idfactory row increment next_id by count increment change_num by 1 where change_num is equal to that read in (1) (3) return next_id read in (1) As far as I see, this is a stored function issue not a Java issue.

As I've complained many times, the current implementaion is far from intuition and this case seems to show that it isn't proper at all either. *lock table* certainly locks idfactory table but the subsequenct *select* sees the table using the snapshot taken before the function call. The *update* statement find the row matching the where clause using the common snapshot but will find the row was already updated and the updated row doesn't satisfy the condition any longer.
