This is not a bug.  You cannot make use of values from one <table
reference> inside the definition of another <table reference>.
So the reference "a.id" is taken to be to a real table named "a",
not to the "a" alias elsewhere in the query.

You could do something like

    SELECT (get_obj(id)).* FROM get_obj_list();

instead.
