       <para>
        Switch logging to quiet mode, producing only one progress message per 5
        seconds. The default logging prints one message each 100,000 rows, which
        often outputs many lines per second (especially on good hardware).

       <para>
        Multiply the number of rows generated by the scale factor.
        For example, <literal>-s 100</literal> will create 10,000,000 rows
        in the <structname>pgbench_accounts</structname> table. Default is 1.
        When the scale is 20,000 or larger, the columns used to
        hold account identifiers (<structfield>aid</structfield> columns)
        will switch to using larger integers (<type>bigint</type>),
        in order to be big enough to hold the range of account
        identifiers.

        Expected values are <literal>range</literal> or <literal>hash</literal>.
