I need to do some timezone manipulation, and I was wondering about this
difference:

australia=# select version();
                           version
--------------------------------------------------------------
 PostgreSQL 7.1.3 on i386--freebsd4.4, compiled by GCC 2.95.3
(1 row)
australia=# select '2002-03-18 00:00:00' at time zone 'Australia/Sydney';
ERROR:  Time zone 'australia/sydney' not recognized
australia=# set time zone 'Australia/Sydney';
SET VARIABLE
australia=# select '2002-03-18 00:00:00';
      ?column?
---------------------
 2002-03-18 00:00:00
(1 row)


Why can't I use 'australia/sydney' as a time zone in 'at time zone'
notation?  Has it been fixed in 7.2?

Now, say I do this:

select '2002-03-18 00:00:00' at time zone 'AEST';

That will give me aussie eastern time quite happily, but what if I don't
know when summer time starts?  I don't want to have to manually choose
between 'AEST' and 'AESST'???  To me, the way to do this would be to use
'Australia/Sydney' as the time zone, but this doesn't work.

7.2 seems to have the same behaviour...
