As we have talked about it before, you know that I agree that the GUC system

Could you clarify this? I can't really believe that people are incapable of
editing a configuration file.

My opinion has always been that we should provide a default file with only the
essential options instead of all of them. I see this as a the major problem,
because people are overwhelmed and consequently don't set anything.

While this is not ideal, I can't really see who this is a major problem, at
least from the perspective of the user.
