Hmm, I bet Antonio is looking for an automatic sequence type, rather
than the 'autogenerated index' that he asks about. That'd be like:

test=> create table A (
test-> B serial,
test-> C text);
NOTICE:  CREATE TABLE will create implicit sequence 'a_b_seq' for SERIAL column 'a.b'
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'a_b_key' for table 'a'
CREATE
test=> 

If you need more, look for "SERIAL" in ther docs.
