Thanks! I was hoping to avoid that, but it's what I wound up doing
after all, as you can see here:
https://github.com/pjungwir/range_agg
In the README I give instructions to create a new aggregate with a
custom range type, and it is actually not bad at all, since the same C
function can serve as implementation in all cases.
Thanks again,
Paul
