I don't like the test cases in the proposed patch.  First, the test
output is excessively large, resulting in a patch with over 30,000
insertions.  I don't think it's a good idea to output the entire tenk1
table.  Second, I don't think it's useful to test json_arrayagg or
json_objectagg.  As I mentioned earlier, these are aggregates, so the
subquery wouldn't be pulled up in the first place.

I've rewritten the test cases, added a commit message, and pushed the
patch.  It has also been back-patched to v16.
