Dead devel-corner links

On the http://www.ca.postgresql.org/devel-corner/
there are some dead links:

Development version of the docs
http://www.ca.postgresql.org/devel-corner/docs/postgres/index.html

http://www.ca.postgresql.org/~vev/regress/

Flowchart of the PostgreSQL backend
http://www.postgresql.org/docs/pgsql/src/tools/backend/index.html

Translating the messages of PostgreSQL programs and libraries

CVS web interface.
http://www.postgresql.org/cgi/cvsweb.cgi/pgsql

CVS repository retrieval
http://www.postgresql.org/devel-corner/docs/postgres/cvs.html

I have also found the following in mail archives
> From: "Dan Wilson" (phpPgAdmin(at)acucore(dot)com)
> Subject: Re: [GENERAL] System tables
> Newsgroups: comp.databases.postgresql.general
> Date: 2001-01-22 08:14:31 PST

> Descriptions of the system tables can be found here:
>
> http://www.postgresql.org/devel-corner/docs/postgres/catalogs.htm

And that link is dead too.

Are those resources moved anywhere, and if so,
where I can find 'em?
