It's no longer there, as fsm was moved from memory (which was limited by max fsm pages) to disk, which is limited by the size of your disks. Most likely you aren't vacuuming aggresively enough. Lower autovacuum_vacuum_cost_delay and raise autovacuum_vacuum_cost_limit, and possibly raise max threads for vacuum works (forget the name) -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
