title: SQL WHERE - Column (value) does not exist
body: <p>I'm attempting to do the most basic WHERE statement in psql and I'm getting a strange error:</p>
  
  <pre><code>ERROR:  column "rom_tut" does not exist
  LINE 1: SELECT * FROM pg_roles WHERE rolname="rom_tut";
  </code></pre>
  
  <p>Why is it complaining that the value isn't a column?</p>
