Our databases are unmanaged, so automatic snapshots, WAL recovery, and PITR aren't available to restore your data unless you've enabled them on the service. Volume backups and point-in-time recovery are both native Railway features on Pro. We don't recover data lost to user-initiated actions. Going forward, enable volume backups on your stateful services so you can self-restore if this happens again.

Is there any other way or paid services available to recover this ?

To correct the earlier message, your postgres service does have a volume attached with data on it, so the data was not on ephemeral storage. However, we do not perform data restoration for user-initiated data loss. There is no paid recovery service available. Going forward, upgrading to Pro unlocks native volume backups and point-in-time recovery on your service, so you can self-restore if this happens again.
