Reject non-ON-SELECT rules that are named "_RETURN". DefineQueryRewrite() has long required that ON SELECT rules be named "_RETURN". But we overlooked the converse case: we should forbid non-ON-SELECT rules that are named "_RETURN". In particular this prevents using CREATE OR REPLACE RULE to overwrite a view's _RETURN rule with some other kind of rule, thereby breaking the view.
