    Description

      With patch for 3984 we removed the check during translation if windowing processing can be done at the end of a PTF chain.
      Should do this check as an Optimization. If plan is:
      PTFOp -> RS -> Extract -> PTFOp
      and partitioning are compatible (ie same or only different in order) plan can be rewritten.
