5907  * should automatically renumber the index of any siblings as needed,
5908  * so that no gaps in the numbering sequence exist after the add/delete
5909  * is completed.
5910  *   What can be added:
5911  *     schema objects
5912  *     backend objects for backend-specific config directives
5913  *     database objects
5914  *     overlay objects
5915  *
5916  *   delete: probably no support this time around.
5917  *
5918  *   modrdn: generally not done. Will be invoked automatically by add/
5919  * delete to update numbering sequence. Perform as an explicit operation
5920  * so that the renumbering effect may be replicated. Subtree rename must
5921  * be supported, since renumbering a database will affect all its child
