Haven't read the patch, but a question seems in order here: should
we regard this as a back-patchable bug fix?  The original example
shows that it's possible to create a zero-column view in existing
releases, which I believe would then lead to dump/reload failures.
So that seems to qualify as a bug not just a missing feature.
On the other hand, given the lack of field complaints, maybe it's
not worth the trouble to back-patch.  I don't have a strong
opinion either way.

BTW, has anyone checked on what the matview code paths will do?
Or SELECT INTO?
