Doesn't help what?
If you mean that the sequence object is still there, you can drop that too.
regression=# create table x(a serial not null);
NOTICE: CREATE TABLE will create implicit sequence "x_a_seq" for serial column "x.a"
CREATE TABLE
regression=# drop sequence x_a_seq;
NOTICE: default for table x column a depends on sequence x_a_seq
ERROR: cannot drop sequence x_a_seq because other objects depend on it
HINT: Use DROP ... CASCADE to drop the dependent objects too.
regression=# alter table x alter a set default 999;
ALTER TABLE
regression=# drop sequence x_a_seq;
DROP SEQUENCE
regression=# \d x
Table "public.x"
Column | Type | Modifiers
--------+---------+----------------------
a | integer | not null default 999
