I think it would be desirable to be able to restrict users from 
"publishing" objects into the public schema. As an admin, I'd like some 
control over the objects in this namespace. Hand-in-hand with this would 
be the ability for the superuser to move (or "promote") an object from a 
private schema to the public one. This would allow a user to develop 
their own objects without interfering with others, but then make it 
public with the superuser's assistance.

The search path you suggest above would then lead to the behavior that 
unqualified references to objects will see my own objects before the 
public ones, and other people's private objects must be explicitly 
qualified.
