Help determining values for max_fsm_pages, max_fsm_relations - Mailing list pgsql-admin

I need some help tuning my free space map.  I have about 275 GB of db's spread
across 3 DB servers.  Unfortunetly, due to design and bandwidth issues, I am
not able to vacuum during business hours, and can only vacuum at night.  I am
trying to get my free space map big enough to hold all of the pages needed so
I can do a normal vacuum most nights and not a full.  Can someone please help
me understand how to see what I should set my max_fsm_pages and
max_fsm_relations to.

I'm running 7.3.4.

Thanks,

Chris
