title: PostgreSQL Age Calculation from date type
body: <p>I have the following table:</p>
  
  <pre><code>CREATE TABLE public.employees
  (
  employee_id integer NOT NULL,
  name text NOT NULL,
  date_of_birth date,
  address text,
  email text,
  CONSTRAINT employees_pkey PRIMARY KEY (employees_id),
  CONSTRAINT employees_email_key UNIQUE (email)
  )
  </code></pre>
  
  <p>How would I be able to list each employee's name with their age in the output?</p>
  
  <p>Thanks.</p>
