i found the problem:
sys=> create table test2(
sys(> id serial,
sys(> name varchar(10),
sys(> primary key(id)
sys(> );
NOTICE: CREATE TABLE will create implicit sequence "test2_id_seq" for
"serial" column "test2.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "test2_pkey"
for table "test2"
CREATE TABLE
sys=> insert into test2 values(1,'myname');
INSERT 18765 1
sys=> insert into test2 (name) values('myname2');
ERROR: duplicate key violates unique constraint "test2_pkey"
sys=>
Why is it so ?
Thanx
Michal
