yes, quite easy.
test=# create table xxx (id serial primary key, val text);
NOTICE: CREATE TABLE will create implicit sequence "xxx_id_seq" for
serial column "xxx.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"xxx_pkey" for table "xxx"
CREATE TABLE
test=# create table yyy (id serial primary key, xxx_id int references
xxx(id));
NOTICE: CREATE TABLE will create implicit sequence "yyy_id_seq" for
serial column "yyy.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"yyy_pkey" for table "yyy"
CREATE TABLE
test=# alter table xxx alter column id type bigint;
ALTER TABLE
test=# alter table yyy alter column xxx_id type bigint;
ALTER TABLE
voila!
