Where can I get a reference manual/pages for all the functions, predefined

I'm getting really tired of looking through four possible sources on
documentation. Bruce's book, postgresql docs: admin, user, programmer.

Thanks.

To answer my own question,
http://www.postgresql.org/devel-corner/docs/user/plpgsql-description.htm
has most of the information I was looking for.
