I don't much like this.

SET search_path TO dontexist, a, b;
CREATE TABLE foo();

And the table foo is now in a (provided it exists). Your proposal would
break that case, right? The problem is that the search_path could come
from too many places: postgresql.conf, ALTER ROLE, ALTER DATABASE etc.

And I have seen roles setup with some search_path containing schema that
will only exist in some of the database they can connect to…
