libpq now always tries to send ALPN. With the traditional negotiated SSL connections, the server accepts the ALPN, and refuses the connection if it's not what we expect, but connecting without ALPN is still OK. With the new direct SSL connections, ALPN is mandatory. NOTE: This uses "TBD-pgsql" as the protocol ID. We must register a proper one with IANA before the release!
