Hi all,
While investigating the causes of the deadlock I
described previously, we noticed that ps output would
often show some postgresql processes doing COMMIT. The
developer in charge of the application(*) assures me
that they are not using transactions (or at least not
in any of the code he checked). My question is, would
postgresql ps string show COMMIT at the end of
INSERT/UPDATE even if explicit transactions are not
used?
(*)I am posting this on behalf of another department,
so I am not entirely familiar with all the crap they
have writing to the database (and, evidently, neither
are they ;-)). I was called in as a resident
postgresql guru. But these problems are so weird that
I need to turn to the experts.
At one point, they had a problem with pqxx library. It
would create pqxxlog_condor table and write some crap
there. This caused a huge performance problem, so
eventually they disabled whatever option was causing
it. However, yesterday I noticed pqxxlog_condor table
in the database. It was empty, so I dropped it. I
checked this morning and it's back again, also empty.
Could COMMITs be coming from the library?
thanks in advance,
Eugene
