Why do you say truncate is non-transactional? Something simple proves that it's not?
wells=# create table foo (f text); wells=# insert into foo values('cat'); INSERT 0 1 wells=# select * from foo; f ----- cat (1 row) wells=# begin; BEGIN wells=*# truncate foo; TRUNCATE TABLE wells=*# rollback; ROLLBACK wells=# select * from foo; f ----- cat (1 row)

Postgres sequences (what backs the serial type) are non-transactional. nextval, setval, et al. Truncate is also non-transactional.
