Hi all,
Today after upgrading to 9.2 from 9.0 I faced a very odd
incompatibility that seems to me as a bug:
smoking_test=# select timeofday(), clock_timestamp();
timeofday | clock_timestamp

As you can see after casting timeofday() to timestamp with time zone
it adds one hour to the timestamp when clock_timestamp() behaves
normally.
Works for me on my time zone:
test=> select timeofday(), clock_timestamp();
timeofday | clock_timestamp
-------------------------------------+-------------------------------

but not when I set to 'Europe/Moscow'
test=> set time zone 'Europe/Moscow';
SET
test=> select timeofday(), clock_timestamp();

Seems the time zone info still thinks Moscow time is being setting
forward an hour for DST when in fact the time remains constant through
the year.
