title: Convert a Text to an Array - PostgreSQL
body: <p>im learning PostgreSQL and i encountered a little Problem.</p>
  
  <p>I have a text like this:</p>
  
  <pre><code>'{1,1}'
  </code></pre>
  
  <p>and want to create an Array that holds my two values, so that i can access them. 
  How do i do that ? 
  I tried</p>
  
  <pre><code>SELECT string_to_array('{1,1}', '{', '}', ',');
  </code></pre>
  
  <p>But that does not seem to work.</p>
