Yeah, I was never for that decision either. Anybody who's sufficiently
hot about it could try submitting a patch and see what happens.

I'm not quite sure how the option should work, but maybe call it
--use-unsafe-path and define it as adopting the same search_path
setting seen at dump time? Or maybe better to provide a restore-time
option saying "use this search_path"? It needs some thought, not
just quick-n-dirty code.
