No, psql isn't the point: we can certainly make its behavior match the
backend's. What I'm wondering about is the effect on random PG-using
applications: should we forbid them from sending multiple SQL commands
per PQexec (or equivalent in other client library APIs)?
Backwards compatibility says no, but you can make some decent arguments
for forbidding it anyway.
