The goal of this repo is to show a minimal reproducable example for an error that ends up killing node when the database is removed on Fly.io.
Run fly launch in this directory.
Note Make sure you say yes to both creating a PostgreSQL database and to deploying.
Run fly logs to view the logs. There should be a fly.toml file in this dir from launching, so it knows what app to show the logs for.
When the app is running, go into the UI and delete the database app.
See fly.logs for an example of what happens, where it fails for a few seconds then the node process terminates.
However, if I remove pg-boss from the app and do the same thing, it does not die, so this doesn't appear to be some Fly.io behavior that somehow notices the DB was deleted and reaps the app. It feels like pg maybe cannot handle a DNS loss of the hostname while running, or we need to trap some error propogation better in pg-boss or the app itself?
