Yeah, I wouldn't propose this if money were the only type we were
thinking of getting rid of; likely not worth the trouble. But I've
got one eye on the geometric types as well --- I think it would be
great all around if we could kick those out of the core distribution
and let them be maintained independently. But I fear we can't do that
without some method whereby pg_upgrade is still possible across the
change.
