This is configurable.  See
http://www.postgresql.org/docs/8.4/static/datetime-config-files.html

In general our intent is not to try to put every timezone abbreviation
in the world into the default list of abbreviations.  That would mostly
have the effect of losing error-checking capability.  It's better to
have a fairly short list of abbreviations your users might actually use.
