4677  *     schema objects
4678  *     backend objects for backend-specific config directives
4679  *     database objects
4680  *     overlay objects

4684  *   modrdn: generally not done. Will be invoked automatically by add/
4685  * delete to update numbering sequence. Perform as an explicit operation
