Hi Andrey,
Thank you for your reply.

Yes, it seems to be the most native way. That's why I needed this
rewritten (mostly copy-pasted) frontend-safe version of parser (guc-file.l).

I am willing to add it to the November commitfest, but I have some
concerns regarding frontend version of GUC parser. Probably, it is
possible to refactor guc-file.l to use it on both front- and backend.
However, it requires usage of IFDEF and mocking up ereport for frontend,
which is a bit ugly.
