I've pushed 0002 with several corrections: it did not seem to me that
you'd correctly propagated what ANALYZE is doing into CREATE INDEX or
pgstattuple.  Also, since one of the things VACUUM does with num_tuples
is to report it as "the total number of non-removable tuples", I thought
we'd better leave that calculation alone.  I made the added code count
live tuples in a new variable live_tuples, instead.
