[aceforeverd]

select ..
from t
window w as (
   union (select .. from t2 last t3 on ...)
   partition by .. order by ...
)

->

AggNode
  RequestUnion
    Request(t)
    Table(t)
    WindowUnions
      SimpleProject
        RequestJoin
          Partition(t2)
          Partition(t3)

• t2 should optimized by window definition
• t3 should optimized by join condition
