      <term><option>--host=<replaceable class="parameter">host</replaceable></option></term>
      <listitem>
       <para>
        Specifies the host name of the machine on which the server is
        running.  If the value begins with a slash, it is used as the
        directory for the Unix domain socket. The default is taken
        from the <envar>PGHOST</envar> environment variable, if set,
        else a Unix domain socket connection is attempted.

      <listitem>
       <para>
        Specifies the TCP port or local Unix domain socket file
        extension on which the server is listening for connections.
        Defaults to the <envar>PGPORT</envar> environment variable, if
        set, or a compiled-in default.

       <para>
        Never issue a password prompt.  If the server requires
        password 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.

       <para>
        Force <application>pg_restore</application> to prompt for a
        password before connecting to a database.
       </para>

       <para>
        This option is never essential, since
        <application>pg_restore</application> will automatically prompt
        for a password if the server demands password authentication.
        However, <application>pg_restore</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.

      <listitem>
       <para>
        Specifies a role name to be used to perform the restore.
        This option causes <application>pg_restore</application> to issue a
        <command>SET ROLE</command> <replaceable class="parameter">rolename</replaceable>
        command after connecting to the database. It is useful when the
        authenticated user (specified by <option>-U</option>) lacks privileges
        needed by <application>pg_restore</application>, but can switch to a role with
        the required rights.  Some installations have a policy against
        logging in directly as a superuser, and use of this option allows
        restores to be performed without violating the policy.
