7271  * should automatically renumber the index of any siblings as needed,
7272  * so that no gaps in the numbering sequence exist after the add/delete
7273  * is completed.
7274  *   What can be added:
7275  *     schema objects
7276  *     backend objects for backend-specific config directives
7277  *     database objects
7278  *     overlay objects
7279  *
7280  *   delete: probably no support this time around.
7281  *
7282  *   modrdn: generally not done. Will be invoked automatically by add/
7283  * delete to update numbering sequence. Perform as an explicit operation
7284  * so that the renumbering effect may be replicated. Subtree rename must
7285  * be supported, since renumbering a database will affect all its child
