Subject: Add unique constraints on columns referenced by foreign keys

Add unique constraints on columns referenced by foreign keys

PostgreSQL correctly throws an error if you try to create a foreign key
and there isn't a unique constraint on the referenced columns, since it
could end up referencing multiple rows.
