       Note that the application must check to see if a new line consists
       of  the  two characters  <code class="literal">\.</code>, which  indicates
       that the server has finished sending the results  of  the
       <code class="command">COPY</code> command.  If  the  application might receive
       lines that are more than <em class="parameter"><code>length</code></em>-1  characters  long,
       care is needed to be sure it recognizes the <code class="literal">\.</code>
