      Description

      With the changes for ReduceSinkDedup it is no longer true that a non Map-side PTF Operator is preceded by an ExtractOp. For e.g. following query can produce the issue:

      create view IF NOT EXISTS mfgr_price_view as 
      select p_mfgr, p_brand, 
      sum(p_retailprice) as s 
      from part 
      group by p_mfgr, p_brand;
              
      select p_mfgr, p_brand, s, 
      sum(s) over w1  as s1
      from mfgr_price_view 
      window w1 as (distribute by p_mfgr sort by p_brand rows between 2 preceding and current row);
      

      Fix is to add an explicit flag to PTFDesc
