Review Comment:
> I assume the partition column is a hour/day transformation on a
timestamp_ns column?
No, it's a partition column without transformation.
> For nano timestamp, users just have to use string literal for now.
This approach doesn't work well on partition columns. I will add a test to
showcase the scenario.
