I haven't looked into the details but - is there a point for us to
remove the requests for renegotiation completely? Will this help those
that *haven't* upgraded their openssl library? I realize it's not
necessarily our bug to fix, but if we can help.. :) If a patched
version of openssl ignores the renegotiation anyway, there's nothing
lost if we turn it off in postgresql, is there?
