5912  * should automatically renumber the index of any siblings as needed,
5913  * so that no gaps in the numbering sequence exist after the add/delete
5914  * is completed.
5915  *   What can be added:
5916  *     schema objects
5917  *     backend objects for backend-specific config directives
5918  *     database objects
5919  *     overlay objects
5920  *
5921  *   delete: probably no support this time around.
5922  *
5923  *   modrdn: generally not done. Will be invoked automatically by add/
5924  * delete to update numbering sequence. Perform as an explicit operation
5925  * so that the renumbering effect may be replicated. Subtree rename must
5926  * be supported, since renumbering a database will affect all its child
