That's a tough one. One way would be to scour the CVS logs: the 
core maintainers usually attribute who a certain change was from. 
How you could automate that is beyond me: I have some ideas, however. 

Another way is to look at the email lists. Since most patches come 
through on the patch list, I did a quick count of distinct "from" 
addresses from that list. My archives only go back about a year: 
in that time, there were 1814 messages from 94 different emails. 
About 24 of those were one-shot wonders, but the usual suspects 
topped the list:

    73 | Neil Conway <neilc@samurai.com>
    83 | Peter Eisentraut <peter_e@gmx.net>
   129 | Joe Conway <mail@joeconway.com>
   307 | Tom Lane <tgl@sss.pgh.pa.us>
   599 | Bruce Momjian <pgman@candle.pha.pa.us>

So I think about 90 is probably a good ballpark to start from, 
as far as the number of people contributing to the code. Assuming 
that almost all of the posters to patches are actually contributing 
something. (By way of comparison, the general list saw @28,000 posts 
from 3200 people!) This is for one year, so a total I would roughly 
guess to be about 2-3 times that. I'll go see what I can do with the 
cvs logs...
