What's about daylight saving time for you?
I'm almost sure the DST boundary is near the date in your example.
However, with 7.3.4 on FreeBSD I get:
fduch=# SHOW TimeZone ; TimeZone
---------------Europe/Moscow
(1 row)
fduch=# SELECT to_timestamp('2004 10 31 00 00 00', 'YYYY MM DD HH MI SS'); to_timestamp
------------------------2004-10-31 00:00:00+04
(1 row)
fduch=# SELECT to_timestamp('2004 11 01 00 00 00', 'YYYY MM DD HH MI SS'); to_timestamp
------------------------2004-11-01 00:00:00+03
(1 row)
So both timestamps before and after boundary are parsed well for me.

Hmm, 7.3 and 7.4 docs say that it returns timestamp (WITHOUT time zone
is default since 7.3 IIRC), but in fact it accepts and returns timestamp
WITH time zone. This is probably a documentation bug...
