Eduoardo, I REALLY suggest you don't use them at all.  You should make a 
primary key like this:

CREATE TABLE blah (
   id SERIAL PRIMARY KEY,
   ...
);

Also note that by default, OIDs are NOT dumped by pg_dump.  You will 
need to add extra switches to your pg_dump backup to ensure that they are.
