      Allow EXPLAIN (ANALYZE, VERBOSE) to display per-worker statistics. · b287df70
      Robert Haas authored 
      The original parallel sequential scan commit included only very limited
changes to the EXPLAIN output.  Aggregated totals from all workers were
displayed, but there was no way to see what each individual worker did
or to distinguish the effort made by the workers from the effort made by
the leader.

Per a gripe by Thom Brown (and maybe others).  Patch by me, reviewed
by Amit Kapila.
