These create table commands succeed, even tho the foreign key refers to a 
'different' type (int2 product_id column refers to an int8 column):

CREATE TABLE products (
    id int8 primary key,
    name text not null
);

CREATE TABLE orders (
    id int8 PRIMARY KEY,
    product_id int2 not null REFERENCES products (id)
);

If I replace int2 with numeric, real, text, etc it fails as expected ("key 
columns are of incompatible types"). 

Expected: integer types should match exactly (or at least be large enough to 
hold the referenced value).

thanks,
