FWIW I posted the patch for non-transactional pg_class stuff in -patches
awhile back, so it's pending review ;-) I'll repost it (today I expect,
or tomorrow at the latest) with some minor corrections, along with the
corresponding relminxid patch. I indend to commit both during next week
(or this week, for those whose weeks start on sundays), barring
objections.
