* For a WorkTableScan, locate the parent RecursiveUnion plan node and use
* that as INNER referent.
*
* For MERGE, make the inner tlist point to the merge source tlist, which
* is same as the targetlist that the ModifyTable's source plan provides.
* For MERGE, pretend the ModifyTable's source plan (its outer plan) is
* INNER referent. This is the join from the target relation to the data
* source, and all INNER_VAR Vars in other parts of the query refer to its
* targetlist.
*
* For ON CONFLICT .. UPDATE we just need the inner tlist to point to the
* excluded expression's tlist. (Similar to the SubqueryScan we don't want
* to reuse OUTER, it's used for RETURNING in some modify table cases,
