You have two services in your project - Postgres and Postgres-mdoW. The Data tab only appears on database services deployed from Railway's database templates. If Postgres-mdoW was deployed from a GitHub repo, it won't have a Data tab since it's not a database service. Your data should be in the original Postgres service. Can you check if the Postgres service has the Data tab and shows your tables?

yeah, so Postgres-mdoW was actually the original database with all the data. It'd been around for months now. I spent all day yesterday trying to connect to it from the app but I couldn't for various SSL reasons and I saw no Data tab at all in the UI.

The other 'Postgres' volume was just something I launched yesterday as a hail mary just to see if I had those same SSL / connection issues as mdoW and it did not. It has none of the original data, which makes me wonder where the original data went.

You are deploying a GitHub repo onto the Postgres service. I have reverted that for you. Your data tab is restored and accessible.

Now, obviously, these are your services, and you are free to do what you want with them, but I would advise not to mess about with services that may hold critical data, as we do not typically help restore something after it has been misconfigured.
