I've looked at the available patches for openssl, and so far can only
see that ssl3_renegotiate returns 0 if a renegotiation is requested,
which would cause pg to throw an error. Is there another patch that
fixes this ? I would have expected openssl to simply ignore this
request if renegotiation is removed from the library ?
