You need a newer version of the zic timezone database. Way newer --- it
looks to me like the first version of the zic files that knows the above
rules is 2007h, which was released today. You'd need to grab
ftp://elsie.nci.nih.gov/pub/tzdata2007h.tar.gz, feed it through zic,
and put the files into place in the Postgres installation tree.

Suggestion: lobby your politicians to set DST transition dates more than
just a month in advance. Or even (heaven forbid) have a law that stays
the same for years at a time. Don't they realize that people have
better things to do than scramble to update their equipment at the last
minute?
