create temp table .. on commit delete rows

1)
# create temp table a ( a int ) without oids on commit delete rows;
# insert into a values(1);
# begin;
# insert into a values(2);
# commit;
# select * from a;
a
---
(0 rows)

2)
# insert into a values(1);
# begin;
# insert into a values(2);
# rollback;
# select * from a;
a
---
(0 rows)

It seems to me that 1) is good, but 2) makes some strange, unpredictable result...
