I'll once again whimper softly and perhaps ineffectually that an
SQL-exposed equivalent like
SET SESSION AUTHORIZATION foo WITH RESET COOKIE 'lkjhikuhoihkihlj';
would seem to suit the same purpose, with the advantage of being
immediately usable by any kind of front- or middle-end code the
instant there is a server version that supports it, without having
to wait for something new at the protocol level to trickle through
to n different driver implementations.
