// We mark all PostgreSQL packages as NeverAutoRemove because otherwise apt
// would remove the old postgresql-x.y package when the "postgresql" meta
// package changes its dependencies to a new version, rendering the old
// database cluster inaccessible. As access to the cluster might depend on
// other modules (like datatypes), we use a pretty wide pattern here. We might
// tighten this to match only actually used PostgreSQL versions in the future.
