How should I calculate the value of max_fsm_pages?
 
Thanks

Because you have more pages that need to be cleaned during the vacuum than you have room for in your configured free space map (max_fsm_pages). To fix, vacuum more frequently, increase your max_fsm_pages and restart postgres, or upgrade to 8.4, which automatically adjusts the FSM as needed under the covers.
