Just thinking more about this. SQL spec > If no row qualifies, then the result of COUNT is 0 (zero), and the result of any other aggregate function is the null value. and this is also about array_agg. So it might be that the `count` is the only aggregate function that really returns non-null values, and maybe we don't need to complicate UDAF API for this. -- This is an automated message from the Apache Git Service.
