Обсуждение: pgsql: Fix thinko in previous patch to always update pg_class.reltuples

Fix thinko in previous patch to always update pg_class.reltuples/relpages.

I mis-simplified the test where ANALYZE decided if it could get away
without doing anything: under the new regime, that's never allowed.  Per
bug #6068 from Jeff Janes.  Back-patch to 8.4, just like previous patch.

Branch
------
REL8_4_STABLE
