I created the following table:
create table xyz (
n serial,
abc character varying,
constraint n_pkey primary key (n));
Each time I do an insert:
insert into xyz(abc) values('adf6');
The field n is not random but is sequential. Is there something I
should do to make the serial number random?
Thanks,

No! No oid, it's deprecated. The solution: use serial.
