Good point.  In theory you could hack the pg_class.relfilenode column
to match the older database, but we have no code to do it.

BTW, I'm also suspicious about whether pg_class.oid !=
pg_class.relfilenode actually works.  I think there may be some places
where we are using one but should be using the other.  I have a TODO
item to grovel through the code and make sure this is all okay, but it's
not going to get to the top of the queue until there's a pressing reason
to do it.

Oh well, another cycle with no pg_upgrade :-(
