> Logical Range node has been added with outputOrdering recently. It's used to
> eliminate redundant Sort during optimization. However, this outputOrdering
> info doesn't not propagate to physical Range node. We should use this
> outputOrdering from logical Range node so parent nodes of Range can correctly
> know the output ordering.
