No, we can't do like this, because we have something like this:

CREATE TABLE test_base (
    id INT
);
CREATE TABLE test_child_with_data (
    t TEXT
) INHERITS (test_base);

ALTER TABLE test_base ADD COLUMN date DATE;

INSERT INTO test_child_with_data VALUES (1, 'text', NOW());

CREATE FUNCTION some_magic() RETURNS SETOF test_child_with_data AS
$$
    SELECT (SUM(id), t, MIN(date))::test_child_with_data
        FROM test_child_with_data
        GROUP BY t
$$ LANGUAGE SQL;


INSERT INTO test_child_with_data
    SELECT * FROM some_magic(); -- Works fine.


-- Dump/restore


INSERT INTO test_child_with_data
    SELECT * FROM some_magic(); -- Error.
