You definitely need to increase the fsm shared memory parameters. The
default max_fsm_relations is just plain too small (try 1000) and the
default_max_fsm_pages is really only enough for perhaps a 100Mb
database. I'd try bumping it to 100,000. Note you need a postmaster
restart to make these changes take effect.
