Not really excited about that.  The contrib regression tests already
exercise the extension functionality, so making into
another one would just reduce the number of code paths being covered.

In any case, if we don't find a way to allow automated testing of
pg_upgrade from the pre-9.1 versions, we have not fixed the problem.
