<literal>columns</literal> option.  Note that <application>psql</application> will
          not attempt to wrap column header titles; therefore,
          <literal>wrapped</literal> format behaves the same as <literal>aligned</literal>
          if the total width needed for column headers exceeds the target.

          <para>
          The <literal>asciidoc</literal>, <literal>html</literal>,
          <literal>latex</literal>, <literal>latex-longtable</literal>, and
          <literal>troff-ms</literal> formats put out tables that are intended
          to be included in documents using the respective mark-up
          language. They are not complete documents! This might not be
          necessary in <acronym>HTML</acronym>, but in
          <application>LaTeX</application> you must have a complete
          document wrapper.
          The <literal>latex</literal> format
          uses <application>LaTeX</application>'s <literal>tabular</literal>
          environment.
          The <literal>latex-longtable</literal> format
          requires the <application>LaTeX</application>
          <literal>longtable</literal> and <literal>booktabs</literal> packages.

          <para>
          Sets the border line drawing style to one
          of <literal>ascii</literal>, <literal>old-ascii</literal>,
          or <literal>unicode</literal>.
          Unique abbreviations are allowed.  (That would mean one
          letter is enough.)
          The default setting is <literal>ascii</literal>.
          This option only affects the <literal>aligned</literal> and
          <literal>wrapped</literal> output formats.
          </para>

          <para><literal>ascii</literal> style uses plain <acronym>ASCII</acronym>
          characters.  Newlines in data are shown using
          a <literal>+</literal> symbol in the right-hand margin.
          When the <literal>wrapped</literal> format wraps data from
          one line to the next without a newline character, a dot
          (<literal>.</literal>) is shown in the right-hand margin of the first line,
          and again in the left-hand margin of the following line.
          </para>

          <para><literal>old-ascii</literal> style uses plain <acronym>ASCII</acronym>
          characters, using the formatting style used
          in <productname>PostgreSQL</productname> 8.4 and earlier.
          Newlines in data are shown using a <literal>:</literal>
          symbol in place of the left-hand column separator.
          When the data is wrapped from one line
          to the next without a newline character, a <literal>;</literal>
          symbol is used in place of the left-hand column separator.
          </para>

          <para><literal>unicode</literal> style uses Unicode box-drawing characters.
          Newlines in data are shown using a carriage return symbol
          in the right-hand margin.  When the data is wrapped from one line
          to the next without a newline character, an ellipsis symbol
          is shown in the right-hand margin of the first line, and
          again in the left-hand margin of the following line.
          </para>

          <para>
          When the <literal>border</literal> setting is greater than zero,
          the <literal>linestyle</literal> option also determines the
          characters with which the border lines are drawn.
          Plain <acronym>ASCII</acronym> characters work everywhere, but
          Unicode characters look nicer on displays that recognize them.
