Start with the programmer's manual from the HTML docs (7.1 has a lot more in
it than previous versions) - check out the developers section on the
postgresql.org website and you can learn some useful stuff from /contrib and
/interfaces.

There's also a developers list that I'm sure can provide help once you've
got the basics down.

When you've fitted all this in your head and can summarise it in a
twenty-line email please feel free to CC: the rest of us :-)
