For Pgx, I want to attempt to upgrade connections to TLS (#391) if support is enabled, but skip STARTTLS if we can't do TLS anyway.

Right now my code to do this tries to configure TLS and catches exceptions, but I'm wondering if there's a more idiomatic way of doing this:

  let upgrade_ssl =
    try
      let config = Conduit_async.V1.Conduit_async_ssl.Ssl_config.configure () in
      `Supported (fun in_channel out_channel ->
        Conduit_async.V1.Conduit_async_ssl.ssl_connect config in_channel out_channel)
    with _ ->
      `Not_supported
