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
