Hi,
I applied your patch and run tpc-h.
Then I got new errors on Q4,12,17 and 19.
ERROR: Aggref found in non-Agg plan node.
See bellow,
----------------------------------
postgres=# \i queries/4.explain.sql
ERROR: Aggref found in non-Agg plan node
STATEMENT: explain analyze select
o_orderpriority,
count(*) as order_count
from
orders
where
o_orderdate >= date '1993-10-01'
and o_orderdate < date '1993-10-01' + interval '3' month
and exists (
select
*
from
lineitem
where
l_orderkey = o_orderkey
and l_commitdate < l_receiptdate
)
group by
o_orderpriority
order by
o_orderpriority
LIMIT 1;

In create_grouping_paths(), we are building partial_grouping_path and same is
used for gather path and other grouping paths (for partial paths). However, we
don't use it for partial path list and sort path due to which path target for
Sort path is different from what we have expected. Is there a problem in
applying partial_grouping_path for partial pathlist? Attached patch just
does that and I don't see error with patch.
With Regards,
Amit Kapila.
