 *
 * NOTES
 *	  Every node type that can appear in stored rules' parsetrees *must*
 *	  have an output function defined here (as well as an input function
 *	  in readfuncs.c).  In addition, plan nodes should have input and
 *	  output functions so that they can be sent to parallel workers.
 *
 *	  For use in debugging, we also provide output functions for nodes
 *	  that appear in raw parsetrees and planner Paths.  These node types
 *	  need not have input functions.  Output support for raw parsetrees
 *	  is somewhat incomplete, too; in particular, utility statements are
 *	  almost entirely unsupported.  We try to support everything that can
 *	  appear in a raw SELECT, though.
