Really?  Works fine for me:

regression=# create sequence foo start with 10;
CREATE SEQUENCE
regression=# select nextval('foo');
 nextval
---------
      10
(1 row)

regression=# select nextval('foo');
 nextval
---------
      11
(1 row)

If you're initializing the sequence some other way, such as with
setval(), maybe you need to make use of the is_called option to setval().
