comment from original postgresql.conf file seems pretty obvious:
#max_fsm_pages = 20000          # min max_fsm_relations*16, 6 bytes each
#max_fsm_relations = 1000       # min 100, ~70 bytes each

basically setting max_fsm_pages to 1000000 consumes 6 megabytes. and i
definitelly doubt you will ever hit that high.
