6246  * should automatically renumber the index of any siblings as needed,
6247  * so that no gaps in the numbering sequence exist after the add/delete

6249  *   What can be added:
6250  *     schema objects
6251  *     backend objects for backend-specific config directives
6252  *     database objects
6253  *     overlay objects
6254  *
6255  *   delete: probably no support this time around.
6256  *
6257  *   modrdn: generally not done. Will be invoked automatically by add/
6258  * delete to update numbering sequence. Perform as an explicit operation
6259  * so that the renumbering effect may be replicated. Subtree rename must
6260  * be supported, since renumbering a database will affect all its child
