Department of second thoughts: the rule that ORDER BY and DISTINCT are
useless for an ungrouped-aggregate query holds regardless of whether
optimize_minmax_aggregates succeeds.  So we might as well apply the
optimization in any case.

I'll leave 8.3 as it was, since this version is a tad more invasive
than my earlier patch.
