Oh. Well, skip the configure part: the only reason there's still a
configure parameter for maxbackends is backwards compatibility with
ancient configure scripts (from days when it was in fact frozen at
configure time). I don't see a need to provide one for reserved_slots.

Probably not. Again, the way that MaxBackends is handled is largely
legacy code. You'd have been better off looking at almost any other
GUC parameter as a template ;-)
