> Currently we disallow queries if the partition specifications of all Wdw fns
> are not the same. We can relax this by generating multiple PTFOps based on
> the unique partitionings in a Query. For partitionings that only differ in
> sort, we can introduce a sort step in between PTFOps, which can happen in the
> same Reduce task.
