(but the easiest thing to have an opinion on ;)

+1 on the feature proposal.

I am a bit torn between "\dcp" (or \dsetting / \dconfig? we don't 
necessarily need for it to be super short) and "\sc". Certainly with 
pattern matching the interface for the "\d" commands would fit that 
pattern. "\sc" would make sense for a thorough introspection of what is 
in the GUC. That said, we get that with SHOW today.

So I'm leaning towards something in the "\d" family.

Thanks,

Jonathan
