So you might want to try 4GB for that one.
Just to confirm, you are using 2 Phase Commit? (People sometimes mistake the max_prepared_transactions setting for something related to prepared statements.) I concur with previous advice that using one regular expression which matches all of the terms is going to be a lot faster than matching each small regular expression separately and then combining them. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
