Ensure that the result tuple of an EvalPlanQual cycle gets materialized
before we zap the input tuple. Otherwise, pass-by-reference columns ofthe result slot are likely to contain just references to the inputtuple, leading to big trouble if the pfree'd space is reused. Pertrouble report from Jaime Casanova. This is a new bug in the recentrewrite of EvalPlanQual, so nothing to back-patch.1 parentf1325ce commitd8e511f
