So, this is a follow-up to #624, right?

What is the reason for defining the PGDATA property? Does it only involve OpenShift scenarios, or baremetal as well?

I noticed it's only defined for containers using postgresql.13.image, does it involve both docker.io/library/postgres:13.6 and registry.redhat.io/rhscl/postgresql-13-rhel7? And postgresql.10.image does not need it?

What about other scenarios, that use PostgreSQL, e.g. PostgresqlMultitenantHibernateIT, or PostgresqlHandlerIT?

Yes, this is basically the same as #624 , but for tests which were missed

Pgdata property points to folder, where postgres stores data. Default location in /var requires advanced rights, which cannot be provided in Openshift, but it works fine in baremetal. Up to this moment, these problems only affected Openshift and library images, so I didn't apply this fix for other combinations.
