Possible bug in 7.4.5

Hi,

I'm using 7.4.5 on a test platform and had a weird behaviour. Here is the
case:

test=# CREATE TABLE t1 (s_no int2 PRIMARY KEY,a varchar(10));
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "t1_pkey"
for table "t1"
test=# CREATE TABLE t2 (s_no int2, x char(2), CONSTRAINT
s_no_exists FOREIGN KEY(s_no) REFERENCES t1 ON UPDATE CASCADE);
test=# INSERT INTO t1 VALUES ('20','test1');
test=# INSERT INTO t1 VALUES ('21','test2');
test=# BEGIN ;
test=# INSERT INTO t2 VALUES ('20','as');
test=# COMM;
ERROR: syntax error at or near "COMM" at character 1
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
test=# COMMIT ;
COMMIT
^^^^^^^^^^^^^^^

Shouldn't it say "ERROR: current transaction is aborted, commands
ignored until end of transaction block" after the commit?

Since COMMIT was executed 'successfully', I thought that t2 has a row
inside, but:

test=# SELECT * from t2 ;
s_no | x
- ----------+---
(0 rows)

Am I missing something, or is it a bug? I can't reproduce it in 8.0beta2.

Regards,
