Is this something we have a fix for or there is no fix yet?

Pavel, it's not so simple as that.  Openshift does things with volume permissions when it provides a persistent volume, so just testing with a standard docker volume is not sufficient to reproduce this.

Well, I don't understand this.  Once you have failed container, you probably
see what are the permissions of data directory so you you can really easily
reproduce that without openshift, or?

This looks like the image in question is missing this update: https://github.com/openshift/postgresql/pull/82
Can someone responsible for the images confirm?

Confirmed.

So this is waiting for the image to be updated?

Note also that there were some permission issues resolved by fixing NFS settings here:
https://bugzilla.redhat.com/show_bug.cgi?id=1282733#c48

which should be applicable to any verification attempt.
