It sounds like a seriously bad idea to use a different parser for

Eh, this is what I suggested in this thread four months ago, though I
didn't remember at the time that aaa6e1def292 had already introduced -C
in 2011. It's definitely the way to go ... all this messing about with
the parser is insane.
Yes, but four months ago recovery options were not a part of GUCs.
OK, if you and Andres are surely negative about solution with parser,
then I will work out this one with postgres -C and come back till the
next commitfest. I found that something similar is already used in
pg_ctl and there is a mechanism for finding valid executables in exec.c.
So it does not seem to be a big deal at the first sight.
Thanks for replies!
