Inconsistency in env variables between upstream postgres image and centos one

[rtnpro]

It seems that centos/postgresql-94-centos7 container uses different but similar environment variables in contrast to upsteam postgres container. This prohibits using centos/postgresql-94-centos7 in application images depending on official postgres container image, e.g.. sentry, without customizing them.

We could use the same nomenclature for the environment variables in the centos based and official postgres container images. This will make adopting centos/postgresql-94-centos7 image much more easier.

• Upstream postgres repo: https://hub.docker.com/_/postgres/
• CentOS postgresql repo: https://hub.docker.com/r/centos/postgresql-94-centos7/

@kbsingh what do you think?

Do you have a patchset we could adopt to be compliant with what is expected?

[rtnpro]

@jperrin I will work on a patch for the fix and send a PR :)
