A connection param can perform more than one attempt more than one ``host`` is provided. Also perform async resolution of the hostname into hostaddr. Because a host can resolve to more than one address, this can lead to yield more attempts too. Raise `OperationalError` if no host could be resolved. Because the libpq async function doesn't honour the timeout, we need to reimplement the repeated attempts.
