This constraint here is funky. Your foreign key column is an auto-generated column that you can't insert directly into. — CONSTRAINT Course_fk FOREIGN KEY(id) REFERENCES Courses(id) on delete cascade on update cascade,. Tension: Your foreign key column is an auto-generated column that you can't insert directly into.

FIXED_BYProblem

ERROR: insert or update on table "course_content" violates foreign key constraint "coursedetail_fk" — INSERT INTO Course_Content(id, section_title) values (id, 'A pretty awesome crash course');. Tension: Key (id)=(1) is not present in table "course_detail". Outcome: Adding this extra column allows the id to point to whatever and not be constrained by the rules of the `SERIAL` data type.

FIXED_BYProblem

you run the risk of getting duplicates — As several comments to your question pointed out. Tension: This will currently not generate an error because you do not have an appropriate constraint on your table. Outcome: Avoiding duplicates requires a table constraint.
