Key validation for GroupWindowAggregate is broken

    Details

      Description

      WindowGroups have multiple equivalent keys (start, end) that should be handled differently from other keys. The UpdatingPlanChecker uses equivalence groups to identify equivalent keys but the keys of WindowGroups are not correctly assigned to groups.

      This means that we cannot correctly extract keys from queries that use group windows.
