We could have a Boolean knob that says "if you don't find the object in
the default schema, search all other schemas".  That should provide all
the backward compatibility we need.  Moreover, I figure if we do it that
way, the whole schema implementation reduces itself mostly to parser work,
no complicated system catalog changes, no complex overhaul of the
privilege system -- at least initially.
