Hello, On applying the patch on latest master branch and running regression tests following failure occurs. I applied it on latest parallel index scan patches as given in the link above.

--- 92,105 ----
explain (costs off)
select sum(parallel_restricted(unique1)) from tenk1
group by(parallel_restricted(unique1));
! QUERY PLAN
! -------------------------------------------------------------------
HashAggregate
Group Key: parallel_restricted(unique1)
! -> Gather
! Workers Planned: 4
! -> Parallel Index Only Scan using tenk1_unique1 on tenk1
! (5 rows)
IIUC, parallel operation being performed here is fine as parallel
restricted function occurs above Gather node
and just the expected output needs to be changed.
Thank you,
