PostgreSQL Data Loss Caused by Broken Railway Template Image

22 days ago

All the AI ​​agent offers me is to delete all the data (thousands of data) and create a new database. It insists there's no other way. But I have clients, I have hundreds of courses on the platform!

I deployed a PostgreSQL database using the official Railway template postgres-ssl:18. The service crashed immediately with a catatonit initialization error—a well-known Docker image bug, NOT a user configuration issue.

When I attempted recovery by creating a new PostgreSQL service with a standard postgres:18-alpine image and remounting the original volume, the new instance cannot authenticate to the existing database because:

The old volume contains a database initialized with the same password

The new PostgreSQL service auto-generates a different password

This creates an irreconcilable password mismatch—FATAL: password authentication failed

The core problem: Railway's postgres-ssl:18 template image is broken and caused data to become inaccessible. I should not have to manually recover from a broken official template.

Current situation:

Production database with live user data is inaccessible

Dependent services cannot deploy

I have no way to reset the password or recover the data without Railway's intervention

What I need:

Immediate assistance recovering the data from the original volume

An explanation of why the official postgres-ssl:18 template is broken

A fix or replacement template that actually works.

I'm very afraid of losing all my data.

Try this:

  1. Disable all public networking on the database if you have any, as the following steps will disable user authentication
  2. SSH into your database service (right click your service and select Copy SSH Command)
  3. Run this command: sed -i 's/host all all all scram-sha-256/host all all ::\/0 trust/' /var/lib/postgresql/data/pgdata/pg_hba.conf (This will bypass user authentication)
  4. Redeploy your database
  5. SSH again, and run the command psql
  6. Run ALTER USER postgres with password '<PASSWORD>'; where <PASSWORD> is the value of the variable PGPASSWORD in your Railway dashboard
  7. Type exit
  8. Run sed -i 's/host all all ::\/0 trust/host all all all scram-sha-256/' /var/lib/postgresql/data/pgdata/pg_hba.conf (This will re-enable user authentication)
  9. Redeploy your database

All the data is lost. Hundreds of courses and users. Thousands of euros spent on creation. I'm shocked. I was sure the railway had backups for this kind of thing.


Have you tried the steps I wrote above with the old volume attached to the new Postgres service?

But this won't help in my case - the problem is not the password, but that the tables don't exist.


You said you still have the original volume...?

When you lose your business due to an infrastructure error, it's time to change it. I needed Railway so I didn't have to worry about deployment and data security. In today's situation (I've already read the forums – it's a global problem), the only option is to simply change the infrastructure.
