5909  * should automatically renumber the index of any siblings as needed,
5910  * so that no gaps in the numbering sequence exist after the add/delete
5911  * is completed.
5912  *   What can be added:
5913  *     schema objects
5914  *     backend objects for backend-specific config directives
5915  *     database objects
5916  *     overlay objects
5917  *
5918  *   delete: probably no support this time around.
5919  *
5920  *   modrdn: generally not done. Will be invoked automatically by add/
5921  * delete to update numbering sequence. Perform as an explicit operation
5922  * so that the renumbering effect may be replicated. Subtree rename must
5923  * be supported, since renumbering a database will affect all its child
