Grab a stack trace and a 'perf top' for forensic analysis in case it happens again 2. Install latest 9.2 binaries 3. Restart database There's not much value in analyzing such an out of date database; there's a very high probability your bug has already been fixed. merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
