5968  * should automatically renumber the index of any siblings as needed,
5969  * so that no gaps in the numbering sequence exist after the add/delete

5971  *   What can be added:
5972  *     schema objects
5973  *     backend objects for backend-specific config directives
5974  *     database objects
5975  *     overlay objects
5976  *
5977  *   delete: probably no support this time around.
5978  *
5979  *   modrdn: generally not done. Will be invoked automatically by add/
5980  * delete to update numbering sequence. Perform as an explicit operation
5981  * so that the renumbering effect may be replicated. Subtree rename must
5982  * be supported, since renumbering a database will affect all its child
