I've committed this with a WARNING during validation and no comment
otherwise.

I left out the proposed regression tests because they fail in "make
installcheck" mode, unless you've previously built and installed cube
and seg, which seems like an unacceptable requirement to me. I don't
think that leaving the code untested is a good final answer, of course.
The idea I was toying with was to create a dummy extension for testing
purposes by means of doing a direct INSERT into pg_extension --- which
is ugly and would only work for superusers, but the latter is true of
"CREATE EXTENSION cube" too. Anybody have a better idea?
