TIMEZONE not working?

Hi!

If I correctly understand v7.4 manual, value, say,
'2003-11-26 12:00' in TIMESTAMP WITHOUT TIMEZONE column
should output '2003-11-26 19:00' for "+08:00" timezone.

The following test results seem to be somewhat unexpected.
Restting OS timezone (/etc/timezone and /etc/localtime in
Linux) does not make the results more comfortable.

The display in Windowz for the result set SELECTed from
PostgreSQL running on Linux is the same as that in psql
prompt - being always UTC value. Query 'SET SESSION TIMEZONE
TO 8' is sent to the backend after the connection with the
backend is established and before query 'SELECT * FROM ..'
is sent to the backend, of course.

Any idea would be much appreciated!
