  <title>Notes</title>

  <para>
   <command>REASSIGN OWNED</command> is often used to prepare for the
   removal of one or more roles. Because <command>REASSIGN
   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>
   <command>REASSIGN OWNED</command> requires privileges on both the
   source role(s) and the target role.
  </para>

  <para>
   The <xref linkend="sql-drop-owned"> command is an alternative that
   drops all the database objects owned by one or more roles. Note
   also that <command>DROP OWNED</command> requires privileges only
   on the source role(s).
  </para>

  <para>
   The <command>REASSIGN OWNED</command> command does not affect the
   privileges granted to the old_roles in objects that are not owned
   by them.  Use <command>DROP OWNED</command> to revoke those
   privileges.
  </para>

  <para>
   The <command>REASSIGN OWNED</command> command does not affect the
   ownership of any databases owned by the role.  Use
   <xref linkend="sql-alterdatabase"> to reassign that ownership.
  </para>
