Does this max_fsm_pages value seem OK for a 46GB database?
I've clustered all the tables that seemed to be exhibiting large amounts
of bloat.
reporting=# SELECT pg_size_pretty(pg_database_size('reporting'));
pg_size_pretty
----------------
46 GB
(1 row)
NOTICE: number of page slots needed (1576544) exceeds max_fsm_pages (204800)
HINT: Consider increasing the configuration parameter "max_fsm_pages" to a value over 1576544.
