I see what you are saying, and this is fine for those cases in which the user
has supplied the schema, but I don't see how it solves the ordering problem.
If I have a table public.foo and greg.foo, and both are "visible", how will
psql know which one to show? It should be showing the first in the schema
search path, in other words, the one that will get effected by a SQL
statement such as "SELECT * FROM foo;" This is of course the original
temp table problem with psql.
At any rate, I will play with the RelationIsVisible stuff when somebody
writes a SQL interface to it (or I write it myself, but that will take
quite a long time :)
