Found a notice after completing the
 vacuumdb -p 5433  -- all --analyze --full -v
max_fsm_relation = 1400 in postgresql.conf
Thou all our 50 db individually have less then 1400 relation , when it
completes , there was NOTICE that increase the max_fsm_relation.
INFO:  free space map contains 10344 pages in 1400 relations
DETAIL:  A total of 25000 page slots are in use (including overhead).
54304 page slots are required to track all free space.
Current limits are:  25000 page slots, 1400 relations, using 299 KB.
NOTICE:  max_fsm_relations(1400) equals the number of relations checked
HINT:  You have at least 1400 relations.  Consider increasing the
configuration parameter "max_fsm_relations".

But there nearly only 300 tables in that db. Is the  free space map is per
DB or for all DB. Can i know the reason of this problem?
