Really? I expected there would be a few issues raised. For one about the need
to use PG_ASYNC from libpq-int.h.
Perhaps what I should do it split it into two patches, one which just adds
\connect& and \S (switch connection) which will be the larger patch because it
has to break out the connection structure like you mention. And a second which
does the asynchronous response handling which is where there may be some
questions about how to handle things.

Ah, but it's not just the comment, if I put an XXX in it's definitely because
there's something I'm not certain about. In this case now that I look at it
again I think it's usually ok to ignore the result but in a session with
ON_ERROR_STOP set (such as one running a script) we would want to exit I
think.
Another XXX is next to the include of libpq-int.h and a third one is where I
have the pg_sleep loop instead of a select/poll loop. It occurs to me now that
that loop should check cancel_pressed too.
