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