Not really. There's some information in the "Internals" section of the
main docs:
http://www.postgresql.org/docs/7.4/static/internals.html
But that could probably do with a lot of improvement.
If you're new to DBMS internals, I'd also suggest picking up a
textbook on the subject. I've personally used "Database Management
Systems" by Ramakrishnan and Gehkre -- it's quite good.
