Description
Continuing from #3751.
- ST_CountAgg
- ST_SummaryStatsAgg
These two aggregates are candidates for parallel aggregation. They are already marked parallel safe in their current incarnation.
They require a combinefunc, and serialize/deserialize functions. Unfortunately each has several different SQL function parameterizations, so it'll be a little complex to carry out.
