As we have talked about it before, you know that I agree that the GUC system 
could use some improvements.  But I'm a bit surprised about some of your 
assessments.

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.

True.  But how does your proposal address this?
