VMware Data Services Manager 2.2
This behavior is by design. Databases deployed via DSM run as containerized services, and the underlying Photon OS functions only as a Kubernetes worker node.
Because of this architecture:
Root database access is intentionally restricted for security and isolation.
The root password is not exposed, accessible, or retrievable.
Only the admin user created at deployment is meant for tenant-level operations.
Tools such as pgAdmin provide standard DB connectivity but do not grant additional privileges or bypass these restrictions.
Use the admin user created at deployment for all supported database operations.
