By definition, only one can be visible: a table named "foo" hides any
other "foo" that's later in the search path. This is exactly the point
that the is_visible tests cover, while there isn't any easy way to
handle it in SQL by comparison of a relnamespace value to a
current_schemas list --- that comparison doesn't tell you anything
about possible conflicting names elsewhere in the search path.
