> Upstream will, in the next release, support date subtraction returning a duration in addition to adding durations or intervals to dates. What‘s the upstream? arrow-rs? >I think the semantics of adding plain integers to dates is suitably opaque that we probably won't support that upstream, but the approach of using a rewrite to convert to a duration makes a lot of sense I also think the semantics of adding plain integers to dates is not suitable for adding in the arrow-rs. The pg https://www.postgresql.org/docs/current/functions-datetime.html support the operation ``` date + integer → date Add a number of days to a date date '2001-09-28' + 7 → 2001-10-05 ``` We can use the rewrite to support them.
