6882  *     schema objects
6883  *     backend objects for backend-specific config directives
6884  *     database objects
6885  *     overlay objects
6886  *
6887  *   delete: probably no support this time around.
6888  *
6889  *   modrdn: generally not done. Will be invoked automatically by add/
6890  * delete to update numbering sequence. Perform as an explicit operation
6891  * so that the renumbering effect may be replicated. Subtree rename must
6892  * be supported, since renumbering a database will affect all its child
6893  * overlays.
6894  *
6895  *  modify: must be fully supported.
