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.
