I agree that some more flexibility in search_path seems reasonable,
but what we've got at the moment is pretty handwavy. Dimitri didn't
suggest what the uses of the different parts of a three-part path
would be, and also failed to say what the implications for the default
creation namespace would be, as well as the existing special handling
of pg_temp and pg_catalog. That stuff all works together pretty
closely; it'd be easy to end up making it less usable not more so.
