Обсуждение: stored procedures

Could someone point me to a tutorial or HOWTO regarding stored procedures?  I
know very little about them and need to learn everything I possibly can about
them as soon as possible.  I looked throught the Postgres docs and couldn't
find anything that goes into them in depth.
   Thank you,
