  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).      For use in debugging, we also provide output
  17  *        functions for nodes that appear in raw parsetrees, path, and plan trees.
  18  *        These nodes however need not have input functions.
