My feeling is that either the view is temporary, fully, or it isn't. I
don't see having it in the public namespace _and_ removing it on session
exit as defensible. I would like to update the TODO list to say:
Place views on temporary tables in temporary namespaces
It may be difficult, but I clearly think it is a bug if we don't do it.
