A conflict handler callback must return one of the following three values.
If CHANGESET_REPLACE is returned by an SQLITE_CHANGESET_DATA conflict handler, then the conflicting row is either updated or deleted, depending on the type of change.
If CHANGESET_REPLACE is returned by an SQLITE_CHANGESET_CONFLICT conflict handler, then the conflicting row is removed from the database and a second attempt to apply the change is made. If this second attempt fails, the original row is restored to the database before continuing.
