Hi nice idea! I'm mostly a DB guy and I also face this kind of challenges because I'll soon need to share my pg codebase over different servers.

Until now I was more investigating the native extension mechanism of PostgreSQL: https://www.postgresql.org/docs/current/static/extend-extens.... But I totally get that a more ad-hoc and versatile solution can be more fitted.

Don't be to rude because it's really minimalist, I actually just published this afternoon my first tiny test on GitHub here : https://github.com/MarHoff/Test

So i definitively had to say Hi there ;)
