Обсуждение: pgsql: Fix assorted confusion between Oid and int32.

Fix assorted confusion between Oid and int32.

In passing, also make some debugging elog's in pgstat.c a bit more
consistently worded.

Back-patch as far as applicable (9.3 or 9.4; none of these mistakes are
really old).

Mark Dilger identified and patched the type violations; the message
rewordings are mine.
