Personally I always thought that was a feature not a bug. If we give
each one its own DB, there will be a couple of dozen databases
cluttering the installation at the end of "make installcheck", and no
convenient way to get rid of them. Moreover, what I think you've got
in mind doesn't work in the "make check" case anyway --- you'd have
little alternative but to test upgrading each one separately.
