The JDBC driver avoids returning all the databases on the server because
it cannot access them. It can only access the current database so that is
all it returns from getCatalogs. We made this decision intentionally to
handle the exact situation that your next getTables call reveals. If we
returned other databases in getCatalogs, people would try to use them in
other database metadata calls which would not work.
