The HEAD of the master branch of the git repository is where
development normally takes place. You should start by developer
section of the main PostgreSQL web site and the pages to which it
links -- especially the Developer's FAQ page:
http://www.postgresql.org/developer/http://wiki.postgresql.org/wiki/Developer_FAQ
You also might want to browse the README files in the source
directories.
