Right you are. I guess the moral of the story is that when using custom
datatypes, search_path is a required setting. I guess that is why the "public"
schema should be just that, completely accessable by any user with rights to
the DB. So, is the best-practice for the my_schema tables to reference the
user-defined datatype in the "public" schema?
CREATE TABLE my_schema.foo (uuid public.uniqueidentifier);
