Creating serial ID on Windows.

I'm having some troubles restoring a database on Windows and I found this difference between PostgreSQL running on Linux and Windows.
When I create a table like this:
CREATE TABLE fee_payment1(id_fee_payment1 serial NOT NULL) WITH OIDS;

On Linux platform it will be:
CREATE TABLE fee_payment1 ( id_fee_payment1 serial NOT NULL) WITH OIDS;

And on Windows platform is:
CREATE TABLE fee_payment1
( id_fee_payment1 int4 NOT NULL DEFAULT nextval('fee_payment1_id_fee_payment1_seq'::regclass) ) WITH OIDS;

So, I would like to know if this would have an impact throught restoring database.
