I used to try and size free space map to be a little bigger than it needed to be. I now size 4 or 5 times what it needs to be. shared memory is cheap. So is going to 8.4, but on legacy systems that you can't upgrade, 8.3 with a huge FSM works well enough (with suitably aggressive autovac). -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
