Right. From a quick grep, it looks like we have seven binaries using
the signal-based cancel handler.

(For programs that only send a cancel request right before they break
the connection, it's probably not worth a huge amount of effort to
change it right away, but for psql in particular I think the status
quo is a little weird.)
