title: List all NON-GENERATED sequences for a schema in PostgreSQL
body: <p>In PostgreSQL there are 2 types of sequences:</p>
  
  <ul>
  <li>Sequences created by the user using CREATE SEQUENCE</li>
  <li>Sequences generated by the DB to back a column of type SERIAL</li>
  </ul>
  
  <p>INFORMATION_SCHEMA.SEQUENCES returns both types of sequences.</p>
  
  <p>What <strong>SQL statement</strong> can get a list of the <strong>sequences created by the user</strong> (WITHOUT the ones generated by the DB) for a specific schema?</p>
  
  <p>P.S.: I'm using PostgreSQL 9</p>
