Inheritance tree is expanded far after where attr_needed for the
parent built, in set_base_rel_sizes() in make_one_rel(). I'm
afraid that building all attr_needed for whole inheritance tree
altogether is a bit suffering.
I have wanted the point of inheritance expansion earlier for
another patch. Do you think that rearranging there? Or generate
them individually in crete_foreign_plan()?
Anyway, I'm lookin forward to your next patch. So no answer
needed.
regards,
