We carry around information about if a given query has row security or not to allow the plancache to use that information to invalidate a planned query in the event that the environment changes. Previously, the flag of one of the subqueries was simply being copied into place to indicate if the query overall included RLS components. That's wrong as we need the global OR of all subqueries. Fix by changing the code to match how fireRIRules works, which is results in OR'ing all of the flags. Noted by Tom. Back-patch to 9.5 where RLS was introduced.
