 second rule for a primary key, not allowing zero, and being covered by an index for faster access. Usage of OIDs has 
 historic reasons, and isn't really first choice for designing user tables. PostgreSQL still uses this for backwards compatibility, 
 and while a newer approach would probably use explicit primary keys it won't be changed now any more.
