This is a small table that takes up 27 pages and it scanned all of them.
You have 1272 rows in it and none of them are dead (i.e. deleted/updated
but still taking up space).

You are tracking ~ 4.6 million pages and have space to track ~ 15.5
million, so that's fine. You are right up against your limit of
relations (tables, indexes etc) being tracked though - 1200. You'll
probably want to increase max_fsm_relations - see manual for details
(server configuration / free space map).
