Concept marked as updated, but no 'Concept replaced by' relationship

@DTorok:

You forgot that there is more than one relationship that indicates an update of a deprecated concept:

SELECT * relationship
WHERE relationship_id IN (
                                  'Concept same_as to',
                                  'Concept alt_to to',
                                  'Concept poss_eq to',
                                  'Concept was_a to'
);

They are less strong than ‘Concept replaced by’ but that’s what we get from the sources.
