Good question.
I don't believe it needs to be while XidGenLock is being held at all;
certainly not in this particular place. All that really matters is that
it happens before any backend starts seeing said xid in tuple headers.
I believe the call can be moved over to AssignTransactionId. I'd
probably put it at the end of that function, but it can go anywhere
between there and where it is now. Do you have any preference?
