Yeah, I agree. Even if we back-patched a code change, nothing could
rely on relhassubclass for this purpose in a v11 database, because
of not knowing whether the user actually bothered to manually update
pre-existing indexes' entries. Better to know that it doesn't work
than to be unsure if it does.
