In my humble opinion, the command:
ALTER TABLE ALTER COLUMN fooser SET DEFAULT nextval('aaa_seq');
should be equivalent to:
ALTER TABLE ALTER COLUMN fooser TYPE integer;
ALTER TABLE ALTER COLUMN fooser SET DEFAULT nextval('aaa_seq');
...ie, if we mess with 'default' it is no longer a serial, but a plain
integer with default sequence.
