How to generate are own apt packages for ubuntu?

[David Grelaud <dgrelaud@xxxxxxxxxxx>]

Hello,

We would like to deploy a modified version of PostgreSQL on our servers. 

It would be easier if we could build our own apt package for Ubuntu 14.04.

We've found this project  : http://git.postgresql.org/gitweb/?p=pgapt.git;a=summary

Is it the right tool? How to use it (without jenkins if possible)?

Is there a better solution?

Thank you,

David Grelaud
