Description
Given this schema:
Parent
name Text
Child
Id (Key Parent)
age Int
This should generate a child table SQL like:
CREATE TABLE child (
id int primary key references parent(id)
age int
As it stands, it correctly creates the column type and datatype, but the foreign key does not get made.

Research direction
Start by locating the schema-generation path for shared primary keys and the code that emits foreign-key references. Reproduce the Parent/Child schema and inspect the generated SQL; done means the child primary-key column also references parent(id) without regressing the existing column type and datatype.
