Uh, no, surely not. The schema itself is re-used if it exists, but all
the contained tables get flushed by the new session (if for some reason
the old session failed to do that, as it would in case of a crash).
Re-use of the schema object is just a minor implementation optimization
--- there's no expectation that temp tables would ever survive into
another session.
