The bottom line is that I intentionally avoided assuming that an agg with an
aggsortop could only be min() or max() and that having an order by clause
would always be harmless in such cases. I can't think of an actual use case
where it would matter, but I've seen people define some pretty strange aggs
recently.
So I mildly object to simply throwing away the ORDER BY clause in such cases.
