Bizarre. On my Fedora 16 box, I see a different misbehavior:

regression=# set timezone to 'Europe/Moscow'; select '2011-03-27 23:00:00'::timestamptz;
SET
timestamptz
------------------------
2011-03-28 00:29:40+04
(1 row)

(W-SU behaves the same, incidentally.) Two other machines are fine
with this case, though. It may or may not be relevant that the F16
build is using --with-system-tzdata, as I imagine your Debian package
is also, while the machines that are happy are not.

So: some platform-specific misbehavior here. I have no time to poke at
it more now, though. Who else can reproduce this, on what platforms?
