i am working on rebuilding the postgres RPM from source code (which has some custom changes) for Cent OS distribution .  I did find  pgdg-centos-96.spec in /pgrpms/rpm/redhat/9.6/pgdg-yum/CTOS-7 from  git://git.postgresql.org/git/pgrpms.git .

However i dont have any clue how to use these , can you help ? I am currently able to rebuild the source with my changes but could not figure out how to package this .

Thanks

Rahul
