[Hackers]Backend quey plan process

Hi, 
     I've been tracing the data structure in the query plan process for a while. But then I found the data structure manipulation is really so confusing. Could some guy tell me where could I find any guide on how to figure out the process and data structure usage? Is there any good resource helping us read the code? 
     BTW, which email system are you using to send to postgres mailing list? As you can keep the top-answering and maintain the title of your email with [hackers] in front, my gmail can not help on that. For this email, I just add by hand.
    Thank you a lot for your help.

maybe you can read:
http://www.pgcon.org/2011/schedule/events/350.en.html, it's still a
mistery for me but this seems more clear than read the code... after
read this, read the README's in the code... read the code :)

You shouldn't add the [Hackers] prefix yourself.  The mail list server
will add it automatically for you.  Gmail deals with this perfectly
fine.
