        <para>
        This command sets options affecting the output of query result tables.
        <replaceable class="parameter">option</replaceable>
        indicates which option is to be set. The semantics of
        <replaceable class="parameter">value</replaceable> vary depending
        on the selected option.  For some options, omitting <replaceable
        class="parameter">value</replaceable> causes the option to be toggled
        or unset, as described under the particular option.  If no such
        behavior is mentioned, then omitting
        <replaceable class="parameter">value</replaceable> just results in
        the current setting being displayed.

          <listitem>
          <para>
          The <replaceable class="parameter">value</replaceable> must be a
          number. In general, the higher
          the number the more borders and lines the tables will have,
          but details depend on the particular format.
          In <acronym>HTML</acronym> format, this will translate directly
          into the <literal>border=...</literal> attribute.
          In most other formats only values 0 (no border), 1 (internal
          dividing lines), and 2 (table frame) make sense, and values above 2
          will be treated the same as <literal>border = 2</literal>.
          The <literal>latex</literal> and <literal>latex-longtable</literal>
          formats additionally allow a value of 3 to add dividing lines
          between data rows.

          <varlistentry id="app-psql-meta-command-pset-columns">
          <term><literal>columns</literal></term>
          <listitem>
          <para>
          Sets the target width for the <literal>wrapped</literal> format, and also
          the width limit for determining whether output is wide enough to
          require the pager or switch to the vertical display in expanded auto
          mode.
          Zero (the default) causes the target width to be controlled by the
          environment variable <envar>COLUMNS</envar>, or the detected screen width
          if <envar>COLUMNS</envar> is not set.
          In addition, if <literal>columns</literal> is zero then the
          <literal>wrapped</literal> format only affects screen output.
          If <literal>columns</literal> is nonzero then file and pipe output is
          wrapped to that width as well.

          Specifies the field separator to be used in
          <acronym>CSV</acronym> output format.  If the separator character
          appears in a field's value, that field is output within double
          quotes, following standard <acronym>CSV</acronym> rules.
          The default is a comma.
