New description:
if you have a DB like that
{{{#!sql
CREATE TABLE foo ( id serial primary key, other_id int UNIQUE);
CREATE TABLE bar (
id serial primary key, other_id int,
constraint myconst
FOREIGN KEY(other_id) references foo(other_id)
);
}}}
the generated model for the bar table will have the other_id be a FK to
foo and not foo(other_id).
I'm attaching a potential fix for this. Sorry I had no time for the UTs.
