        Vacuum all four standard tables before running the test.
        With neither <option>-n</option> nor <option>-v</option>, <application>pgbench</application> will vacuum the
        <structname>pgbench_tellers</structname> and <structname>pgbench_branches</structname>
        tables, and will truncate <structname>pgbench_history</structname>.

       <para>
        Length of aggregation interval (in seconds).  May be used only
        with <option>-l</option> option.  With this option, the log contains
        per-interval summary data, as described below.

       <para>
        Exit immediately when any client is aborted due to some error. Without
        this option, even when a client is aborted, other clients could
        continue their run as specified by <option>-t</option>
        or <option>-T</option> option, and <application>pgbench</application>
        will print an incomplete results in this case.
       </para>
       <para>
        Note that serialization failures or deadlock failures do not abort the
        client, so they are not affected by this option.

        Set the filename prefix for the log files created by

      <listitem>
       <para>
        Enable retries for transactions with serialization/deadlock errors and
        set the maximum number of these tries. This option can be combined with
        the <option>--latency-limit</option> option which limits the total time
        of all transaction tries; moreover, you cannot use an unlimited number
        of tries (<literal>--max-tries=0</literal>) without
        <option>--latency-limit</option> or <option>--time</option>.
        The default value is 1 and transactions with serialization/deadlock
        errors are not retried. See <xref linkend="failures-and-retries"/>
        for more information about retrying such transactions.

       <para>
        When showing progress (option <option>-P</option>), use a timestamp
        (Unix epoch) instead of the number of seconds since the
        beginning of the run.  The unit is in seconds, with millisecond
        precision
