It was intentionally omitted in the original design, on the grounds that
after a single-table VACUUM there's no very good reason to think that
the global FSM stats are sufficiently complete to be accurate. Of
course, in a multi-database installation the same charge could be
leveled against the situation after a single-database VACUUM, so maybe
there's not a lot of strength in the argument.
IIRC the code change would be trivial, it's just a matter of judgment
whether the extra output is useful/trustworthy.
