Nope, doesn't meet the spec requirements. One thing we can certainly
say is that there would have to be a notion of an "active catalog"
(which could be determined by outside-the-spec means, perhaps a GUC
variable) because "CREATE SCHEMA foo" would have to create foo as a
child of the active catalog.

I'm also fairly unclear on what this implies for search_path searches.
Currently, as soon as you have more than one dotted name, search_path
is ignored ... but should it be used? Maybe "a.b" ought to be sought
as "foo.a.b" for successive values of "foo" from the search path.
