  <title>Description</title>

  <para>
   <application>dropuser</application> removes an existing
   <productname>PostgreSQL</productname> user.
   Superusers can use this command to remove any role; otherwise, only
   non-superuser roles can be removed, and only by a user who possesses
   the <literal>CREATEROLE</literal> privilege and has been granted
   <literal>ADMIN OPTION</literal> on the target role.
  </para>

  <para>
   <application>dropuser</application> is a wrapper around the
   <acronym>SQL</acronym> command <link linkend="sql-droprole"><command>DROP ROLE</command></link>.
   There is no effective difference between dropping users via
   this utility and via other methods for accessing the server.
  </para>
