Broken attachment links in PG mail archives

I went to
http://archives.postgresql.org/pgsql-hackers/2009-02/msg00109.php
and clicked on the "attachment" link about halfway down the page,
and got "404 Not Found".  Another message in the same thread,
http://archives.postgresql.org/pgsql-hackers/2009-02/msg00000.php
has two attachments ... the first one works while the second gives
"403 Forbidden" !?

These three attachments seem to have different mime types; not sure
whether that's affecting it.  Anyway, I'd really like to have
access to those attachments ...
