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. regards, tom lane
