Tom Lane 115f414124 Fix VACUUM's reporting of dead-tuple counts to the stats collector. ... Historically, VACUUM has just reported its new_rel_tuples estimate (the same thing it puts into pg_class.reltuples) to the stats collector. That number counts both live and dead-but-not-yet-reclaimable tuples. This behavior may once have been right, but modern versions of the pgstats code track live and dead tuple counts separately, so putting the total into n_live_tuples and zero into n_dead_tuples is surely pretty bogus. Fix it to report live and dead tuple counts separately. This doesn't really do much for situations where updating transactions commit concurrently with a VACUUM scan (possibly causing double-counting or omission of the tuples they add or delete); but it's clearly an improvement over what we were doing before.
