Tom Lane de0227d8ae Fix old oversight in join removal logic. ... Commit 9e7e29c75a introduced an Assert that join removal didn't reduce the eval_at set of any PlaceHolderVar to empty. At first glance it looks like join_is_removable ensures that's true --- but actually, the loop in join_is_removable skips PlaceHolderVars that are not referenced above the join due to be removed. So, if we don't want any empty eval_at sets, the right thing to do is to delete any now-unreferenced PlaceHolderVars from the data structure entirely. Per fuzz testing by Andreas Seltenreich. Back-patch to 9.3 where the aforesaid Assert was added.		2015-08-06 22:14:28 -04:00
