I agree.
A good way how to describe a config variable is present for 
listen_addresses, which clearly states the default value. Could be even 
shorter, e.g.
port = 5432 # default: 5432

To solve the "commenting out a setting doesn't return to default' 
problem a magic word 'default' could be introduced, forcing to load the 
default setting.

How about *requiring* to set any variable, at least to xxx='default'? 
This would remove any ambiguities (and force to review postgresql.conf 
after upgrading, which is a good idea anyway).
