Won't it be better if we distinguish between "default" and "current" value of a parameter with '-' (for the "current") and '+' (for the "default") characters? For example: \c + - hst Connect to "default" database with "current" user on host hst. (Omitted values can be treated as "current".) \c + + hst - Connect to "default" database with "default" user on host hst on "current" port. So we'll still have chance to get back to the libpq defaults.
