This is a known problem.  It's fixed for 7.5 but there seems no way to
back-port the fix into existing release series (without forcing initdb).

The error is essentially that the use of an INSERT command as the rule
body causes the original view to be checked for INSERT rather than
UPDATE permissions ...
