6946  * should automatically renumber the index of any siblings as needed,
6947  * so that no gaps in the numbering sequence exist after the add/delete

6949  *   What can be added:
6950  *     schema objects
6951  *     backend objects for backend-specific config directives
6952  *     database objects
6953  *     overlay objects
6954  *
6955  *   delete: probably no support this time around.
6956  *
6957  *   modrdn: generally not done. Will be invoked automatically by add/
6958  * delete to update numbering sequence. Perform as an explicit operation
6959  * so that the renumbering effect may be replicated. Subtree rename must
6960  * be supported, since renumbering a database will affect all its child
