Tom,
How to check if the value it's enough ? The log generate by vacuum verbose
can help ?
The current values for:
max_fsm_pages = 1048576
max_fsm_relations = 1000
this is enough ?
Regards,
Rodrigo

It sounds like you may not have the FSM settings set large enough for your
database. The default settings are only enough for a small DB (perhaps a
few hundred meg).
