4672  * should automatically renumber the index of any siblings as needed,
4673  * so that no gaps in the numbering sequence exist after the add/delete
4674  * is completed.
4675  *   What can be added:
4676  *     schema objects
4677  *     backend objects for backend-specific config directives
4678  *     database objects
4679  *     overlay objects
4680  *
4681  *   delete: probably no support this time around.
4682  *
4683  *   modrdn: generally not done. Will be invoked automatically by add/
4684  * delete to update numbering sequence. Perform as an explicit operation
4685  * so that the renumbering effect may be replicated. Subtree rename must
4686  * be supported, since renumbering a database will affect all its child
