> 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. This is a good point @seddonm1 - I am just starting to look at this pR, but I wonder if we could do something like have a default implementation for `func(scalar, scalar)`, `func(scalar, array)`, and `func(array, scalar)` that are implemented in terms of the `func(array, array)` that way we would only have to supply `func(array, array)` and the scalar input case could be handled on a case by case basis. I'll try and commend inline if I see how that might be done ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
