6950  * should automatically renumber the index of any siblings as needed,
6951  * so that no gaps in the numbering sequence exist after the add/delete
6952  * is completed.
6953  *   What can be added:
6954  *     schema objects
6955  *     backend objects for backend-specific config directives
6956  *     database objects
6957  *     overlay objects
6958  *
6959  *   delete: probably no support this time around.
6960  *
6961  *   modrdn: generally not done. Will be invoked automatically by add/
6962  * delete to update numbering sequence. Perform as an explicit operation
6963  * so that the renumbering effect may be replicated. Subtree rename must
6964  * be supported, since renumbering a database will affect all its child
