title: Export text content to text file without \n mark
body: <p>When I try to export the text content of a field, and that content have carriage return characters, that chars are output like \N string.</p>
  
  <p>For example:</p>
  
  <pre><code>create table foo ( txt text );
  insert into foo ( txt ) values ( 'first line
  second line
  ...
  and other lines');
  copy foo ( txt ) to '/tmp/foo.txt';
  </code></pre>
  
  <p>I want to return the following (a):</p>
  
  <pre><code>first line
  second line
  ...
  and other lines
  </code></pre>
  
  <p>But, output is (b): </p>
  
  <pre><code>first line\Nsecond line\N...\Nand other lines
  </code></pre>
  
  <p>Anybody knows how to get the (a) output?</p>
