Broken links on main site and other issues

Just had a brief nose around the site and found some issue.

On http://www.postgresql.org/about/users the following links are broken:

Institut de Biologie et Chimie des Protéines article
University of Alabama, Birmingham documentation
OmniTI case study

On http://www.postgresql.org/about/quotesarchive the link to the
Database Hacker's Handbook is broken.

I don't know if this right or not, but the license info on
http://www.postgresql.org/about/press/presskit84.html.en (BSD) doesn't
match the main license page: http://www.postgresql.org/about/licence
(PostgreSQL)

On http://www.postgresql.org/community/international the link to the
Turkish PostgreSQL site comes up with an Apache test page:
http://www.postgresql.org.tr/

The alphas page contains redundant info about 9.0a4:
http://www.postgresql.org/developer/alpha which is linked to by this
page: http://www.postgresql.org/developer/testing

For some reason, the Turkish press kit on
http://www.postgresql.org/about/press/ is served with the text/troff
mime type.  Is this normal?
