In my opinion, we plan on accomplishing this by using a container; it's not quite something we have today, but this is good feedback. :)

On Ubuntu/Debian, Postgres doesn't typically work this way, so it's not the way that pgxman works. pgxman works on top of the existing `postgresql` packages and with the existing package manager (apt) in order to install extensions -- which is also how it handles runtime dependencies, whether libraries or even other extensions.

So, that said, we have a container feature I could see using to effectively isolate for a single project. Right now there is only one single "global" container (per Postgres version) that pgxman will manage for you, but this is just a MVP of this feature. I could definitely see something like `pgxman c dev` or similar which will read a local pgxman pack file (pgxman.yaml) in your project and boot a "local" Postgres for you just for that project.

The pgxman pack is already a thing and is how the local container config is maintained, but we haven't tied it together in the way described above... yet. For more on both pgxman pack and the container feature, check out our docs.
