Postgres service is online and persistent volume appears intact, but DB password no longer matches Railway variables after a failed rotation attempt.
No backups visible on current plan. I need official non-destructive recovery guidance for postgres-ssl template.
I cannot share details publicly. Would upgrading to a paid plan provide private support or direct recovery assistance for this case?

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

I found older Railway threads mentioning:
Service panel → Database → Credentials → regenerate password.
However, on my postgres-ssl:18 service I only see:
Deployments / Database / Backups / Variables / Metrics / Settings
There is no visible “Credentials” tab or reset option.
Can Railway staff confirm:
1. where this option exists for postgres-ssl template
2. whether upgrading to Pro exposes it
3. or if manual recovery is the only safe path

Additional finding:
Inside the service panel → Database tab, Railway shows:
- Deployment Online
- Required Variables
- Database Connection → "Attempting to connect to the database..."
There is still no visible Credentials / Reset Password / Regenerate Password option for this postgres-ssl:18 template.
This strongly suggests the service variables exist, but the real postgres password stored in the persistent volume no longer matches them.
Can Railway staff confirm the official non-destructive recovery path for this template?
