      In PUP-6028 error handling for attempts to form relationships with undef resources was improved. This in turn led to a problem with code using {{create_resources}} and the stdlib functions {{ensure_resource}}, {{ensure_resources}}, and {{ensure_packages}} as this combination could feed an undef resource reference into the catalog, and such are now always treated as an error.

      The problem manifests itself as the error message:
      {code}
      No title provided and "" is not a valid resource reference
      {code}

    Description

      Since PUP-6028, catalog compilation now fails when a resource has the require or before metaparameters set to undef.

      This behaviour was relied upon in the puppetlabs-postgresql module at https://github.com/puppetlabs/puppetlabs-postgresql/blob/4.7.1/manifests/server/extension.pp#L57-L58 where the value of the metaparams is worked out in the manifest and can be undef.

      A simple reproducer, at commit eff7ac6 or master:
