I am not sure about 8.3 but certainly earlier releases of PostgreSQL
would have specific dependency issues when a sequence was applied to a
a column after the fact, versus using the serial or bigserial
psuedo-types.

You still get an error if creating a table that specifies a sequence that does not exist yet. I like to control the name of the sequence, plus the starting values or change the incrementing values.
I might have read something wrong but using serial tells PostgreSQL to automatic transforms.
CREATE TABLE tablename ( colname SERIAL
to
CREATE SEQUENCE tablename_colname_seq;
CREATE TABLE tablename ( colname integer NOT NULL DEFAULT nextval('tablename_colname_seq'));
I copied this from the help files.
