Need info on installer - Mailing list pgsql-general

Hi,
Greetings!!!

We have developed a software which uses PostgreSQL as one of the component.
We would like to delever PostgreSQL along with our software as a single package. So we have to create an installer which installs PostgreSQL with all pre-install configuration first and then our software.

Could you help me how to create a single installer? could you send PostgreSQL install script.

Thanks
Ram
