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!
