Again, no JDBC info here, but ...
I did (this is all done in PgAdmin):
create table mytable
( name varchar(60), pk serial primary key )
and this was reported:
NOTICE: CREATE TABLE will create implicit sequence "mytable_pk_seq"
for serial column "mytable.pk"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"mytable_pkey" for table "mytable"
So I went and looked for the sequence and found:
CREATE SEQUENCE mytable_pk_seq
INCREMENT 1
MINVALUE 1
MAXVALUE 9223372036854775807
START 1
CACHE 1;
So it did create a sequence for the serial type. I could then do inserts like:
insert into mytable (name) values ('michael')
and it would increment the values.
