I tried to issue the vacuum command on one of my database and i got the
following log messages:

LOG: max_fsm_relations(1000) equals the number of relations checked
HINT: You have at least 1000 relations. Consider increasing the
configuration parameter

I suspect I must increase max_fsm_relations.
The value of max_fsm_pages is 20000 (the default value).
I suspect I must change this to a higher value... but how high should
this value be?

Thank you in advance,
