Functions documentations

Hi !!

I am looking for a complete list of functions we have under PostgreSQL.

Where can I found this documentation ?

If there is no documentation, I would be please to write one with samples.
In this case, send me your
experience with source for each functions you have try at my direct e-mail.
And I will update this
documentation weekly.


PS: For my personnal use, I have already make a small CookBook of PostgreSQL
(100 pages) with
lots of samples I have found reading the mailing-list and my own experience.


Regards,

Stephane FILLON.
