Query parent table and get child tables columns

I have two tables, one inherits the other:

CREATE TABLE parent (
    col1 INTEGER
);

CREATE TABLE child (
    col2 INTEGER
) INHERITS( parent );

Is there any way to query the parent table, such that it gets all of the columns of the child tables

// Insert some data
INSERT INTO parent( col1 ) VALUES( 1 );
INSERT INTO child( col1, col2 ) VALUES( 2, 2 );

// This query returns just the parent columns
SELECT * FROM parent;

| col1 |
| ---- |
| 1    |
| 2    |

// My desired query would return all columns in parent and child
SELECT.... // Some query, with desired result:

| col1 | col2 |
| ---- | ---- |
| 1    | NULL |
| 2    | 2    |
