Hm, maybe I just don't know how to read their output, but it's not
obvious to me where they are doing the min/max aggregates.

I don't think it's a configuration issue, it's a quality-of-plan issue.
Could you put together a self-contained test case for this problem? I
don't have the time or interest to try to reverse-engineer tables and
test data for these queries --- but I would be interested in finding out
where the time is going, if I could run the queries.
