[ thinks for a bit... ] Might be worth double-checking that pg_upgrade doesn't get confused in a cross-version upgrade. A quick grep doesn't find that it refers to DLSUFFIX anywhere, but it definitely does pay attention to extensions' shared library names.
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.
