Please help, I have persisted it, but the table and data are not restored after restarting the container.

[llnancy]

verion: postgres:15-alpine

Persistent mount (Similar to the following, I am sure that the persistent mounting of the data volume is successful):

volumeMounts:
- name: postgresql
  mountPath: /var/lib/postgresql

After restarting the container, the files in the directory are still there,

but the previous database and table are gone. Is there a way to restore it? How can I do it?
