Dify crushed with no message, i found that some container could not restart, Including the database

The database logs are like this:

initdb: error: directory "/var/lib/postgresql/data/pgdata" exists but is not empty
initdb: hint: If you want to create a new database system, either remove or empty the directory "/var/lib/postgresql/data/pgdata" or run initdb with an argument other than "/var/lib/postgresql/data/pgdata".
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

And i did not find the directory. Thank you for take care of this.

solution: in docker-compose.yaml, the mount directory is "./volumes/db/data:/var/lib/postgresql/data", clean this directory using "rm -rf ./volumes/db/data". Reload the containers.
