I'm not sure what the best thing to do is here, but the reality is
that there are many places where 32-bit XIDs are going to be showing
up for years to come. With the format printed as a raw 64-bit
quantity, people troubleshooting stuff are going to spend a lot of
time figuring what x%2^32 is. And I can't do that in my head. So I
think saying that the proposal does not makes sense is a gross
overstatement. It may not be what we want to do. But it definitely
would make sense.
