Not sure about that last bit.  pg_upgrade has the issue of possibly
wanting to deal with 2 installations, unlike the rest of the tree,
so I'm not sure that fixing its problem means there's something we
need to change everywhere else.

(IOW, keep an eye on the cross-version-upgrade tests while
you mess with this...)
