PL/pgSQL Cookbook

Hi;

I have been writing a ton of PL/pgSQL lately. It seems like there is
probably a lot of code out there that would be of general use to
other people. I looked around for a "postgres cookbook" but only
found a few dead links.

There is one on
http://techdocs.postgresql.org/oresources.php
(http://www.brasileiro.net/postgres/cookbook)
which is not working.

Am I just looking in the wrong place?

I posted a function a few weeks ago -- week_start() to find the
first date in a given year/ week -- but never saw any responses.
Is anyone else interested in sharing functions?

Seems like this would fit well on techdocs. Is something like this
planned for the new collaborative website framework?
