So, have you looked in the docs?

I go here:

http://www.postgresql.org/docs/8.1/static/index.html
see this down the page a bit:
http://www.postgresql.org/docs/8.1/static/storage.html
which takes me here:
http://www.postgresql.org/docs/8.1/static/storage-page-layout.html

And it seems to have that information in it.

Again.  You can look at the source, or find out experimentally by
building tables and checking their size.  Some of this is an inexact
science because different architechtures have different alignment
requirements.
