   > @jorgecarleitao -- I agree with @Dandandan -- think `date_trunc(scalar, array)` and `date_trun(scalar, scalar) are the really important cases. I have no use case for `date_trunc(array, array)`
   
   Having been trying to implement a lot of the Postgres logic recently they all logically support the use of arrays for each of the parameters (i.e. `date_trunc(array, array)`) I have no idea how common the use of this functionality really is - and I suspect it is low - but if we are building the API for Postgres compatibility it would be good to solve.
