  <para>
   <command>DROP OWNED</command> drops all the objects within the current
   database that are owned by one of the specified roles. Any
   privileges granted to the given roles on objects in the current
   database or on shared objects (databases, tablespaces, configuration
   parameters) will also be revoked.

      (see <xref linkend="ddl-depend"/>).

  <title>Notes</title>
  <para>
   <command>DROP OWNED</command> is often used to prepare for the
   removal of one or more roles. Because <command>DROP OWNED</command>
   only affects the objects in the current database, it is usually
   necessary to execute this command in each database that contains
   objects owned by a role that is to be removed.
  </para>

  <para>
   Using the <literal>CASCADE</literal> option might make the command
   recurse to objects owned by other users.
  </para>

  <para>
   The <link linkend="sql-reassign-owned"><command>REASSIGN OWNED</command></link> command is an alternative that
   reassigns the ownership of all the database objects owned by one or
   more roles.  However, <command>REASSIGN OWNED</command> does not deal with
   privileges for other objects.
  </para>

  <para>
   Databases and tablespaces owned by the role(s) will not be removed.
  </para>

  <para>
   See <xref linkend="role-removal"/> for more discussion.
  </para>

  <title>Compatibility</title>

  <para>
   The <command>DROP OWNED</command> command is a
