4665  * should automatically renumber the index of any siblings as needed,
4666  * so that no gaps in the numbering sequence exist after the add/delete
4667  * is completed.
4668  *   What can be added:
4669  *     schema objects
4670  *     backend objects for backend-specific config directives
4671  *     database objects
4672  *     overlay objects
4673  *
4674  *   delete: probably no support this time around.
4675  *
4676  *   modrdn: generally not done. Will be invoked automatically by add/
4677  * delete to update numbering sequence. Perform as an explicit operation
4678  * so that the renumbering effect may be replicated. Subtree rename must
4679  * be supported, since renumbering a database will affect all its child
