      Description

      As discussed in TAJO-1517,
      INTERSECT ALL needs new physical operator,
      which returns the exact number of overlapping rows between results of two query blocks.
      For example, when query1 returns

      1, 3, 3, 3
      

      while query2 returns

      3, 3
      

      query1 INTERSECT ALL query2 should return

      3, 3
      

      INTERSECT can be implemented by selecting distinct result of above physical operator.
