I probably should drop both the inheritance and the citation_id
altogether, and operate with two separate tables:
CREATE TABLE relation_citations (
relation_fk INTEGER REFERENCES relations (relation_id),
source_fk INTEGER REFERENCES sources (source_id),
CONSTRAINT PRIMARY KEY (relation_fk, source_fk)
);
CREATE TABLE event_citations (
event_fk INTEGER REFERENCES events (event_id),
source_fk INTEGER REFERENCES sources (source_id),
CONSTRAINT PRIMARY KEY (event_fk, source_fk)
);
Is there an easy and non-disruptive way to do this?
