Hello,
I'm a SRE and would love to get application names everywhere but depending on developers time, not all apps have set the right setting in the connection string.

If it's set, could it be possible to read from PGAPPNAME environment variable (see libpq's doc) to automatically add it in the ApplicationName field of the connection string?

It's easier/faster for us to push such environment variable (managed through k8s helm chart) than having a patch in the code

Does it sound right? If yes, I could try to implement a PR for it 😄
Thanks!
