Oh, I hadn't looked closely enough to notice that the only reference
there was
Assert(TransactionIdIsValid(RecentGlobalXmin));
I agree: that is just about utterly useless. Let's revert my patch
and remove that Assert. I'm not eager to encourage people to reference
the xmin globals if we don't have to.
