4666  * should automatically renumber the index of any siblings as needed,
4667  * so that no gaps in the numbering sequence exist after the add/delete
4668  * is completed.
4669  *   What can be added:
4670  *     schema objects
4671  *     backend objects for backend-specific config directives
4672  *     database objects
4673  *     overlay objects
4674  *
4675  *   delete: probably no support this time around.
4676  *
4677  *   modrdn: generally not done. Will be invoked automatically by add/
4678  * delete to update numbering sequence. Perform as an explicit operation
4679  * so that the renumbering effect may be replicated. Subtree rename must
4680  * be supported, since renumbering a database will affect all its child
