authentication and a password is not available by
        other means such as a <filename>.pgpass</filename> file, the
        connection attempt will fail.  This option can be useful in
        batch jobs and scripts where no user is present to enter a
        password.

        This option is never essential, since
        <application>pg_receivewal</application> will automatically prompt
        for a password if the server demands password authentication.
        However, <application>pg_receivewal</application> will waste a
        connection attempt finding out that the server wants a password.
        In some cases it is worth typing <option>-W</option> to avoid the extra
        connection attempt.
