Ugh, right. I think we had this discussion before actually, I'd just
forgotten it.

Hm ... doesn't fix the problem for existing dump files, which are going to
say "search_path = foo, pg_catalog". However, we could modify it a bit,
so that the marker is put on schemas that can be skipped if missing for
creation purposes. Then the default could look like "search_path =
!$user, public", while we still get safe behavior for pg_dump's commands.
