Let's create a basic users table with sample data:

CREATE TABLE users (  
  id    serial PRIMARY KEY,
  name  text

INSERT INTO users ('name') VALUES ('Bob'), ('Tom'), ('Sam');  

Then SELECT * FROM users to see what we're working with:

 id | name
  1 | Bob
  2 | Tom
  3 | Sam

Now check out what happens when we SELECT users FROM users:


That's pretty interesting! Postgres returns a tuple containing all of the columns for each row in users.
