Since the OP has apparently already managed to get updated tzdata files
installed on his system, he could just copy them into
/usr/share/postgresql/timezone --- anything using zic should be a
compatible file format.

The lack-of-ARST-on-input problem can be addressed by mucking with
/usr/share/postgresql/timezonesets/Default, if you're using 8.2.
In earlier versions the table is hardwired into datetime.c :-(
