Start with the "internals" section of the SGML docs:
http://developer.postgresql.org/docs/postgres/internals.html
After you've absorbed whatever seems useful to you there,
start reading the source code.  In particular there are a lot
of README files scattered through the source tree that go into
more detail than the SGML docs, and we also make an effort to have
well-commented source code.
