Got any indexes? The more indexes you have to update the slower it's gonna be. You can test this, it's easy to create test rows like so: insert into test select generate_series(1,10000); etc. There's lots of examples floating around on how to do that. So, make yourself a couple of tables and test it. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
