Isn't the post-parse-analysis tree far more interesting? There's
already debug support for printing that.
Of course, you can call pprint() from anyplace using gdb, so for
occasional debugging needs I think no special code support is needed.
I think what you are proposing is something equivalent to the
debug_print_parse GUC, and I'm not sure it's worth that.
