Tom Lane f0271cb154 Reject cases where a query in WITH rewrites to just NOTIFY. ... Since the executor can't cope with a utility statement appearing as a node of a plan tree, we can't support cases where a rewrite rule inserts a NOTIFY into an INSERT/UPDATE/DELETE command appearing in a WITH clause of a larger query. (One can imagine ways around that, but it'd be a new feature not a bug fix, and so far there's been no demand for it.) RewriteQuery checked for this, but it missed the case where the DML command rewrites to *only* a NOTIFY. That'd lead to crashes later on in planning. Add the missed check, and improve the level of testing of this area. Per bug #17094 from Yaoguang Chen. It's been busted since WITH was introduced, so back-patch to all supported branches.
