Packaging - Packages names consistency (RPM)

Hi Hackers,

First, thanks for working on such a great database! :)

We're currently trying to automate our PostgreSQL setup by using Ansible.
We have an Ansible role for which we can specify supplemental extensions
for which a deployment must install.

To keep it simple across deployed version we simply ask to specify
extension list, as simple as:

- pgaudit
- postgis
- wal2json
- ... and so on ...

In the installation steps, we simply install all of these packages and add
the version to the name. But it appears that some package names are either:

- <package>_<version>
- <package><version>

So, it is impossible to simply ask the package/extension name and
programmatically add the version using a common pattern. I think that if we
use the underscore to specify the version, it should be the same across all
versions.

Maybe I'm missing something
Thanks
