The "pages used" sentence above is wrong, and it seems the computation
is wrong too.  I just connected to another database, created, inserted,
and deleted rows from a table and see:

        INFO:  free space map: 50 relations with free space, maximum of 1000 
        relations trackable
        INFO:  17266 pages stored, 18016 pages used (with overhead)
        INFO:  18784 pages required to store all freespace, maximum of 18000
        pages allocatable (171 kB)
        NOTICE:  the number of page slots needed (18784) exceeds max_fsm_pages
        (18000)
        HINT:  Consider increasing the configuration parameter 
"max_fsm_relations"
        to a value over 18784.

The 'pages used' is greater than 18000, which isn't possible.  Seems I
have more work to do.
