Allow EXPLAIN (ANALYZE, VERBOSE) to display per-worker statistics. 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.
