While I was going through this patch, I observed one invalid ASSERT in the function “ExecInitFunnel” i.e.
Assert(outerPlan(node) == NULL);
Outer node of Funnel node is always non-NULL and currently it will be PartialSeqScan Node.
May be ASSERT is disabled while building the code because of which this issue has not yet been observed.
Thanks and Regards,
