And the people expecting the living relation between table a and table
b. So when I do ALTER a.a, then b.a should be changed. What if I drop
a.a or drop a?
So this is reason, why I don't would this feature in SQL side.
I don't buy that. plpgsql doesn't work that way, so why would this?
*especially* with the %TYPE decorator.
Now, if the syntax was
CREATE TABLE b(a a.a)
then I would expect b.a to be a foreign key reference to a.
