I increased the FSM and restarted postgres several weeks ago, and the
toast tables continue to just grow and grow.  I set it to:

max_fsm_relations = 1000    # min 10, fsm is free space map
max_fsm_pages = 100000      # min 1000, fsm is free space map

Now, my table with only 107490 rows takes 20GB on disk.  I dumped and
reloaded the database and got 18.5GB free space back.

I really think this is a bug in the implementation.
