Hello all. I have a number of tables that are actually dictionaries. This means that, in order to keep the reference integrity, in a number of other tables I have FK definitions like these ones:
CREATE TABLE dict1 ( d1 TEXT PRIMARY KEY, ... ); CREATE TABLE user1 ( d1 TEXT NOT NULL REFERENCES dict1 DEFAULT 'value1' ); I am trying to simplify this thing by defining DOMAINs with the proper "NOT NULL" and "DEFAULT" predicates. But it seems there's no way to CREATE a DOMAIN with a "REFERENCES ..." predicate, possibly in the optional CHECK. At the moment I have solved the issue with a function that CHECKs for the VALUE being already in the proper dictionary. But this way I loose the explicit reference integrity. Is there any better advise for this need?
