Description: Making an inherited table to a view causes could not
open relation error in base table
Details:

Steps to reproduce:

CREATE TABLE base( name TEXT );
CREATE TABLE child() INHERITS( base );

CREATE RULE "_RETURN" AS ON SELECT TO child DO INSTEAD SELECT 'Chunky
Bacon'::text AS name;

SELECT * FROM child;
SELECT * FROM ONLY base;
-- the next query causes the error
SELECT * FROM base;

After dropping child queries to base work again.
