>
> Currently COUNT DISTINCT and PERCENTILE functions use a VARBINARY for their
> aggregators to keep enough state for the final merge on the client. The type
> of the final calculation must currently match the type of the aggregators
> which causes these functions to return unreadable results when using sqlline.
> Instead, we should allow the type of the function to differ so these can be
> BIGINT typed as expected.
