If we had that, it wouldn't be a hack. Putting in a hack to cover the
specific case of relistemp, on the other hand, is just a hack.
The real question here, IMO, is "how many applications are there that
really need to know about temporary relations, but have no interest in
the related feature of unlogged relations?". Because only such apps
would be served by a compatibility hack for this. An app that thinks it
knows the semantics of relistemp, and isn't updated to grok unlogged
tables, may be worse than broken --- it may be silently incorrect.
