Thank you but in our appliance, we are not running postgres as a service, we are running it programatically with this script, call postmaster to start it for instance instead of using the service framework. Is there an equivalent in 9.x or does it now have to run as a service.
It is not surprising that a piece of code no longer required by the package for its main operation has not been maintained (maybe it has, I'm not familiar with the Centos assets).
PostgreSQL is capable of being launched in any number of ways. But as you move toward minority status (which initd on Centos 7 seems to be) the wealth of third-party maintained stuff to pick from tends to decrease.
