David Li commented on ARROW-11090:
----------------------------------
Postgres's behavior matches what
[Java|https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html#plusMonths-long-]
and
[dateutil|https://dateutil.readthedocs.io/en/stable/relativedelta.html#examples]
do, so that makes sense.
