New credentials don't update after redeploy

Problem description: We used a password regeneration tool for the root user of our database. However, after the process was completed, Railway redeployed the database, but the new password was not applied correctly; the connection still works only with the old password.

Expected behavior: The newly generated password should be applied correctly, and the old password should no longer be valid.

Current behavior: The database was redeployed, but it continues to use the old password.

Hi, here's the guide I always give.

⠀

Before you do any of this, disable all public access domains. Just in case.

⠀

  1. Install the Railway CLI. You can do so here: https://docs.railway.com/guides/cli

  2. Copy the SSH command by right clicking the PostgreSQL service

  3. Once you're in, type in the following command: (Copy paste this EXACTLY as written.)

    sed -i 's/host all all all scram-sha-256/host all all ::\/0 trust/' /var/lib/postgresql/data/pgdata/pg_hba.conf

  4. Redeploy your database.

  5. Use the SSH command again, and once you're in, type psql.

  6. Type the following SQL command. my_password should be replaced with whatever it actually says in your variables tab for your password (Probably under the PGPASSWORD variable.)

    ALTER USER postgres with password 'my_password';

  7. Type exit

  8. Reset your authentication settings with the following command:

    sed -i 's/host all all ::\/0 trust/host all all all scram-sha-256/' /var/lib/postgresql/data/pgdata/pg_hba.conf

  9. Redeploy your database once again. You have now changed the password.

⠀

Let me know if this works!
