bray=# create table junk (id serial, name text);
NOTICE:  CREATE TABLE will create implicit sequence 'junk_id_seq' for SERIAL 
column 'junk.id'
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'junk_id_key' for 
table 'junk'


bray=# insert into junk (name) values ('Fred');
INSERT 194510 1
bray=# select * from junk;
 id | name 
----+------
  1 | Fred
(1 row)


bray=# select setval('junk_id_seq',5);
 setval 
--------
      5
(1 row)

bray=# insert into junk (name) values ('Joe');
INSERT 194511 1
bray=# select * from junk;
 id | name 
----+------
  1 | Fred
  6 | Joe
(2 rows)
