title: Linking textfile instead of writing much text in a script
body: <p>I use Polygons (WKT) in a where clause. These Ploygons often have big amounts of text, so I want to put them into a textfile and &quot;link&quot; this textfile instead of writing all the text in my script. Is it possible to do this? And: I have read-only access to the postgresql database.</p>
  <p>Example:</p>
  <pre><code>where true
  and st_contains(
          st_setsrid(
              st_geomfromtext('multipolygon(((
  
                      13.xxx 52.xxx
  
                  )))'
              ),  
          4326), 
          st_setsrid(
              st_makepoint(mytable.longitude, mytable.latitude), 
          4326)
      );
  </code></pre>
  <p>The &quot;13.xxx 52.xxx&quot; stands for the big text blocks, here the textfile must be linked.</p>
