  13  * NOTES
  14  *        Every node type that can appear in stored rules' parsetrees *must*
  15  *        have an output function defined here (as well as an input function
  16  *        in readfuncs.c).  In addition, plan nodes should have input and
  17  *        output functions so that they can be sent to parallel workers.
  18  *        For use in debugging, we also provide output functions for nodes
  19  *        that appear in raw parsetrees and path.  These nodes however need
  20  *        not have input functions.
