    # Official Postgres image from DockerHub.
    # The registry prefix 'docker.io' may be required for alternative container engines
    # such as podman unless the user configures a list of registries to be searched.
    # An incorrect or intentionally malicious user configuration can result in
    # security vulnerabilities if the wrong prefix is selected on the user's machine
    # resulting in the possiblity of a malicious image spoofing an official image, which
    # can potentially give an attacker full root access to the server depending on the
    # configuration. Including the prefix in the image key here prevents the container
    # engine from searching any user-defined registries.
    # See https://man.archlinux.org/man/containers-registries.conf.5.en#Short-Name_Aliasing
    # for more information.
