Thread: 7.3.2 client connecting to 7.2.1 server problem
I have the following packages installed on my system:
libpq3: 7.3.2r1-5
python-pygresql: 7.3.2r1-5
postgresql: 7.2.1-2woody2
postgresql-client: 7.2.1-2woody2
In my application, which is written in python, I get a "server closed the
connection unexpectedly" exception after executing a few sql commands. I
print each query before I execute it (debugging) so I tried executing the
queries through psql with no problems.
Is there a known incompatibility between the versions of client/server that
I'm using? Or a known bug in pygresql?
I tried looking for an option to turn on query logging (I thought one was
present), but for some reason I didn't notice it. Is there a way to log
queries without restarting the server? It's a little troublesome for me to
start and stop the server (it's a production server), but I will if
necessary.
Here are the queries that execute (field names have been obfuscated):
BEGIN;
SELECT active FROM process WHERE xx='aa' FOR UPDATE;
UPDATE process SET active='t' WHERE xx='aa';
COMMIT;
-- server dies while trying to execute query below
SELECT bb.id as id,first,last,type from bb,cc where bb.id=bb_id order by dd
asc limit 1;
Sometimes, strangely, it makes it to a point further in the application but
crashes there instead one a different query (all the same program inputs).
I can't reproduce this result, although I recall it happening twice.
I've been using all that software together for quite some time with no
problems until now.
Any advice is appreciated.
Regards,
Jeff

Hmm. What do you see in the postmaster log when this happens?
BTW, you *really* should update to 7.2.4. There are nasty bugs in
7.2.1. There's not enough info here to guess whether you are hitting
a known bug, though.

It looks as though I made the dependencies too loose in that testing release. > In my application, which is written in python, I get a "server closed the > connection unexpectedly" exception after executing a few sql commands.

Or a known bug in pygresql? I suggest you upgrade to the version from unstable (7.3.4-5). Testing is held up and isn't getting timely upgrades; I would not, myself, consider it as good as unstable until we get very close to a new Debian release. Unstable has versioned python packages. If you want woody versions of the postgresql packages, you can get them with this apt line: deb http://people.debian.org/~elphick/debian main -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "But my God shall supply all your need according to his riches in glory by Christ Jesus."
