Description (last modified by pramsey)

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.
