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.
