I thought we did:

    Clean up EXPLAIN's handling of per-worker details.

    Previously, it was possible for EXPLAIN ANALYZE of a parallel query
    to produce several different "Workers" fields for a single plan node,
    because different portions of explain.c independently generated
    per-worker data and wrapped that output in separate fields.  This
    is pretty bogus, especially for the structured output formats: even
    if it's not technically illegal, most programs would have a hard time
    dealing with such data.
