Can't you just add this to your create table:
CREATE TABLE tablename (
colname SERIAL
, check (colname>0 and colname < 32768));
);
With this constraint, whether the storage space requirement would reduce?
OR
Is it just for validation of data?

Well, there's smallserial when creating tables...
create table test(a smallserial);
NOTICE: CREATE TABLE will create implicit sequence "test_a_seq" for serial column "test.a"
CREATE TABLE
Table "public.test"
Column | Type | Modifiers
--------+----------+--------------------------------------------------
a | smallint | not null default nextval('test_a_seq'::regclass)
