Fix Var handling for security barrier views
In some cases, not all Vars were being correctly marked as having beenmodified for updatable security barrier views, which resulted in invalidplans (eg: when security barrier views were created over top ofinheiritance structures).In passing, be sure to update both varattno and varonattno, as _equalVarwon't consider the Vars identical otherwise. This isn't known to causeany issues with updatable security barrier views, but was noticed asmissing while working on RLS and makes sense to get fixed.Back-patch to 9.4 where updatable security barrier views wereintroduced.
