I wonder why SortState is a ScanState. As far as I know ScanState
means the node may need projection and/or qualification, or it scans
some relation, but Sort actually doesn't do such things. I also tried
to modify SortState as PlanState as in the attached patch and
regression test passed. Do I misunderstand ScanState?
