      First phase of implementing hash-based grouping/aggregation. An AGG plan · f6dba10e
      Tom Lane 提交于
      node now does its own grouping of the input rows, and has no need for a
      preceding GROUP node in the plan pipeline.  This allows elimination of
      the misnamed tuplePerGroup option for GROUP, and actually saves more code
      in nodeGroup.c than it costs in nodeAgg.c, as well as being presumably
      faster.  Restructure the API of query_planner so that we do not commit to
      using a sorted or unsorted plan in query_planner; instead grouping_planner
      makes the decision.  (Right now it isn't any smarter than query_planner
      was, but that will change as soon as it has the option to select a hash-
      based aggregation step.)  Despite all the hackery, no initdb needed since
      only in-memory node types changed.
