I think that the core extension stuff and pg_dump stuff is pretty close. It's the upgrade stuff that's thorny. And really, this is a pretty well-known problem. Surely someone has done some research to solve it?

Anyway, IMHO, try to get CREATE EXTENSION into 9.1, perhaps put off ALTER EXTENSION UPGRADE to 9.2.
