You can turn on log duration, which will just log the duration of queries. That's a handy little metric to have and every so often I turn it on and chart average query run times etc with the actual queries. I also turn on logging long running queries of say 5 or 10 seconds or more. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
