      Description

      select count(*) from large1 
      inner join small1 on large1_id = small1_id
      left outer join large2 on large1_id = large2_id 
      left outer join small2 on large1_id = small2_id
      

      Current tajo planner makes the plan as following. All large tables(large1, large2) are scanned in a single execution block. Each table should have a execution block.
