title: Query Parameters in PGAdmin
body: <p>Most GUI SQL Consoles allow the use of parameters/placeholders as follows</p>
  
  <pre><code>SELECT * FROM USERS WHERE USER_NAME = :USER_NAME;
  </code></pre>
  
  <p>You are usually (e.g. Toad, IntelliJ, etc.) presented with a dialog where you have to enter a value for each parameter. However, in PGAdmin I get a syntax error. Is this not supported in PGAdmin or do they use a different syntax?</p>
