Yeah, this looks perfectly normal. VACUUM doesn't make the next-XID
counter go backwards. What it will do from time to time is push out the
wraparound limit (by "freezing" very old rows' XID numbers). As long as
there's a few million transactions' worth of daylight between the wrap
limit and current XIDs, there's nothing to worry about.
