      To implement join pushdown, a foreign data wrapper will typically
      construct an alternative local join plan which is used only for
      rechecks; this will become the outer subplan of the
      <literal>ForeignScan</>.  When a recheck is required, this subplan
      can be executed and the resulting tuple can be stored in the slot.
      This plan need not be efficient since no base table will return more
      than one row; for example, it may implement all joins as nested loops.
