I was thinking about documenting that you can issue "SHOW
default_whatever" and get the result from there. It isn't the handiest
of the procedures, OTOH it's also not a very common use case not
knowing what the level is and wanting to know it - the biggest use
case is just to set the level desired and use the connection. This
possibility is not available with "autocommit" instead, as it's
something all internal to the connection object and not related to the
PG session.
