title: Create insert-only table in PostgreSQL
body: <p>Is there an SQL statement to create an insert-only table in PostgreSQL (v9.5); in other words, with write permissions it is possible to add rows, but not possible to change existing rows?</p>
  
  <pre><code>CREATE TABLE public.newtable
  </code></pre>
  
  <p>Tables are only updated with <code>INSERT</code> statements, not using <code>UPDATE</code> or <code>DELETE</code> statements.</p>
