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.
