I think we can ignore the search_path for this discussion. That's not a
problem of variables vs tables, but just a search path related problem.
It is exactly the same thing right now, when you create a new table x(x)
in a schema which happens to be earlier in your search path.

The objection to the proposed approach for variables was that it would
introduce *new* ambiguities, which Alvaro's suggestion avoids.
