Hi,
I searched www.google.com for "POSTGRES source code" and the first
item was titled "Postgres Source Code" PostgreSQL7.1 Documentation,
pointing to
http://www.postgresql.org/devel-corner/docs/postgres/source.htm (404!
Page not found)
Also, browsing your site, I came across
http://www.postgresql.org/docs/devhistory.html which links to
http://www.postgresql.org/docs/backend/index.html (404! Page not
found)
Thanks for maintaining an informative site!
