Remarks

This enforcement of uniqueness of keys applies only to the primary key, the behavior of insertions into secondary databases is not affected. In particular, the insertion of a record that would result in the creation of a duplicate key in a secondary database that allows duplicates would not be prevented by the use of this flag.
