pg_upgrade just checks that it can "LOAD" whatever it finds in probin.
So this will work if extensions use the recommended extension-free file
names. If they don't, they should get a clean failure.
If this becomes a problem in practice, we could make pg_dump
automatically adjust the probin on upgrade from an old version.
I have committed this now. We can see how it goes.
