Uh-oh. That's my first 'gotcha' in PostgreSQL.
I added the following constraints:
ALTER TABLE relation_citations ADD CONSTRAINT unique_relation_citation_id UNIQUE (citation_id);
ALTER TABLE event_citations ADD CONSTRAINT unique_event_citation_id UNIQUE (citation_id);
And I hope that will be sufficient.
