RULE regression test fragility?

While reviewing the Network Stats Traffic patch I discovered the current
regression test for rules depends on the system view definitions not
changing:

--
-- Check that ruleutils are working
--
SELECT viewname, definition FROM pg_views WHERE schemaname <>
'information_schema' ORDER BY viewname;

In this particular case new fields have been added to the view, breaking
this apparently unrelated test. Is checking the definition of all views
necessary for this test? Would it possibly be better to create a temporary
view for this check, or is something else going on here?
