Thank you for your feedback.
Do you think we don't need int64 GUCs just now, when 64-bit
transaction ids are far from committable shape?  Or do you think we
don't need int64 GUCs even if we have 64-bit transaction ids?  If yes,
what do you think we should use for *_age variables with 64-bit
transaction ids?
