title: Postgres real rounds to 4 decimal places
body: <p>I have a column <code>latitude</code> of type <code>real</code> in my Postgres table.</p>
  
  <p>Looking at it in Postico, it has the value of <code>57.70887</code>.
  But selecting it from psql or via code, the value returned is rounded to 4 decimal places:</p>
  
  <pre><code># SELECT latitude from categories where id = 4;
  
   latitude
  ----------
    57.7089
  (1 row)
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Postgres 9.6.</p>
