Nick Pope fee8734596 Refs #10929 -- Deprecated forced empty result value for PostgreSQL aggregates.
This deprecates forcing a return value for ArrayAgg, JSONBAgg, and
StringAgg when there are no rows in the query. Now that we have a
``default`` argument for aggregates, we want to revert to returning the
default of ``None`` which most aggregate functions return and leave it
up to the user to decide what they want to be returned by default.
