Looks like vacuum verbose doesn't report the number of relations necessary on
version 8.2.7. It just reports the max_fsm_relations value instead:
INFO: free space map contains 113311 pages in 10000 relations
DETAIL: A total of 252816 page slots are in use (including overhead).
252816 page slots are required to track all free space.
Current limits are: 600000 page slots, 10000 relations, using 4587 kB.
NOTICE: max_fsm_relations(10000) equals the number of relations checked
HINT: You have at least 10000 relations. Consider increasing the
configuration parameter "max_fsm_relations".

8.2.7
Does it do this in more recent versions of 8.2 or 8.3?
