\dconfig is generated by querying pg_settings and this
requires a halthy connection. The parameters being proposed with
\conninfo+ are set in libpq by the server [1] and can be retrieved
even if the connection breaks.
Some of these parameters may overlap \dconfig, but I don't see
that as a problem.
