This will give you relation, which you can cross reference against pg_database and pg_class system tables -- that should give a few clues. You can also break down various things interacting with the database by role. For example, have the website auth into the database with a 'website' role, backend reporting scripts with 'reports', etc. That way pg_stat_activity might tell you the specific trouble maker that is doing this. After that, it's about finding the bug -- are you using connection pooling? Begin w/o commit is a grave application error and you should consider reworking your code base so that it doesn't happen (ever). merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
