Unsurprisingly-in-retrospect, buildfarm member crake is now bitching
that cross-version pg_upgrade fails, since it's trying to test importing
back-branch regression DBs that contain tables with the desupported types.

Perhaps the best fix for this is to teach the cross-version-upgrade
buildfarm module to drop the affected tables from the old DB before
testing pg_upgrade. However, that does nothing to help manual testing
of similar scenarios.

Another idea would be to put table drops into the back branch regression
tests, so that their ending states don't include any such tables. That
would cripple pg_dump testing of these types in the back branches, but
I'm not sure if we really care much.

I don't especially like either of these choices --- anyone got another
idea?
