4898  * should automatically renumber the index of any siblings as needed,
4899  * so that no gaps in the numbering sequence exist after the add/delete
4900  * is completed.
4901  *   What can be added:
4902  *     schema objects
4903  *     backend objects for backend-specific config directives
4904  *     database objects
4905  *     overlay objects
4906  *
4907  *   delete: probably no support this time around.
4908  *
4909  *   modrdn: generally not done. Will be invoked automatically by add/
4910  * delete to update numbering sequence. Perform as an explicit operation
4911  * so that the renumbering effect may be replicated. Subtree rename must
4912  * be supported, since renumbering a database will affect all its child
4913  * overlays.
4914  *
4915  *  modify: must be fully supported.
