Ah, nice. I didn't realize that we'd added that. But I'm not sure that
it helps here, because I think we need to compute the end of the
range, not just test whether something is in a range. Like, if someone
wants monthly range partitions starting on 2020-01-01, we need to be
able to figure out that the subsequent months start on 2020-02-01,
2020-03-01, 2020-04-01, etc. Is there a way to use in_range to achieve
that?
