EXPLAIN - SetOp
Combines two datasets for set operations like UNION, INTERSECT, and EXCEPT. Note that the query structure for SetOps is different than you may expect: rather than being the direct parent of the sets on which it operates, a SetOp node only has a single Append child, which has a Subquery Scan for each node to combine.
