I know this question has been asked repeatedly but not fully answered. I have a postgres running in as root user in a container which is using the persistent volume. But it seems like there is permission issue in mounting in the container.

Here are container logs:

`The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

fixing permissions on existing directory /data ... ok
initdb: could not create directory "/data/pg_xlog": Permission denied
initdb: removing contents of data directory "/data"`
