Yeah, it's harder to work on, or maybe just different, but I guess the docs, info(searchable docs, posts, experience), and tooling are lacking.

What's the story for version control, debugging, testing, releasing? It'd be cool to have everything together for data locality and simplifying the stack, but it feels you'd lose a lot of useful knowledge about how to do stuff "properly".

Contributor here. Good points, we do need to develop some best practices around managing function versioning and lifecycle for pg_durable.

https://github.com/microsoft/duroxide - also OSS, the durable execution framework pg_durable is built on itself supports function versions. We can leverage that to get similar support in pg_durable.
