Where is the source code for v8.4.5

Hmm..... then isnt there anyway for me to get the source code... I
could always pull it out of some source rpms from a centos repo.  But
I would like to get my hands on the official source package supplied
by postgres.

Would the source files in SRPMs be the same as the one available in
the postgres download mirrors?
