After some thought, I don't think that's the right approach. It adds
another way search path can be changed, which adds to the complexity.

Also, by default it's "$user", public; and given that "public" was
world-writable until recently, that doesn't seem like a good idea for a
change intended to prevent search_path manipulation.
