Where is the state stored? In my own pg instance? Or is it stored somewhere in the cloud? Also, a small sample code snippet would be helpful.

The state can be stored in any Postgres instance, either locally or in any cloud.

For code, here's the bare minimum code example for a workflow:

  class Example {
    @DBOS.step()
    static async step_one() {
      ...
    }

    @DBOS.step()
    static async step_two() {
      ...
    }

    @DBOS.workflow()
    static async workflow() {
      await Example.step_one()
      await Example.step_two()
    }
  }

Then we have a bunch more examples in our docs: https://docs.dbos.dev/.
