Composite key as foreign key

Hi!

There is not yet a method to assign compound foreign keys to reference with another table

Currently there is only one forge method to assign primary keys as compounds. addKey() 


I think there should be a method that works similarly but for foreign keys, to have a result like this:

Code:

create table Music (
    type char(1) not null check (type = 'M'),
    id integer not null,
    primary key (type, id),
    foreign key (type, id) references Product
);
