A sequence don't guaranteed a gapless behavior.
Simple example:
test=# create table gap (id serial);
NOTICE: CREATE TABLE will create implicit sequence "gap_id_seq" for
serial column "gap.id"
CREATE TABLE
test=*# insert into gap values (default)
test-# ;
INSERT 0 1
test=*# commit;
COMMIT
test=# insert into gap values (default);
INSERT 0 1
test=*# insert into gap values (default);
INSERT 0 1
test=*# rollback;
ROLLBACK
test=# insert into gap values (default);
INSERT 0 1
test=*# commit;
COMMIT
test=# select * from gap;
id
