test=# create table xyz (id int not null);
CREATE TABLE
test=# create sequence xyz_seq;
CREATE SEQUENCE
test=# alter table xyz alter column id set default nextval('xyz_seq');
ALTER TABLE

or:

test=# drop TABLE xyz;
DROP TABLE
test=# create table xyz (id int not null, foo varchar);
CREATE TABLE
test=# alter table xyz alter column id set default nextval('xyz_seq'), alter column foo set default '';
ALTER TABLE
