I think that code probably originated at a time when palloc(0) threw an
error, and was meant to avoid any corner-case failures in the subsequent
logic.  I can't get very excited about the case --- it seems to me the
*real* fix for this complaint is to give hstore some ANALYZE support ---
but if you've tested that it behaves sanely with no columns I have no
objection to committing it.
