libpq is the only client library that doesn't already *have* an API spec
for this.  SET is not helpful for any of the rest because it is not the
spec they need to meet.

Hm.  Is anyone else very concerned about that?  The design roadmap I put
forward last week suggested reporting client encoding and autocommit
status during the initial connection handshake, but not after every
query.  Neither of those seem like things that are sensible to change
on-the-fly during a session.
