By and large there is no part of the backend that is designed to be run
standalone --- almost everything relies on palloc and elog, for instance.
I concur with the suggestion to consider doing this as a backend
function rather than in a standalone program.

Note that what raw_parser gives you is the raw grammar output, which is
probably not really what you want. For almost any sort of interesting
analysis, I'd think you'd want to run the syntax tree through
parse_analyze() or one of its siblings, so that semantic interpretation
gets done. There is definitely no hope of pulling out parse_analyze(),
because it has to consult the catalogs ...
