Not really excited about that. The contrib regression tests already
exercise the extension functionality, so making pg_regress.so 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.
