[SOLVED] Undefined method

I’m using the postgres community cookbook which is just a collection of custom resources. I keep getting the following error:
undefined method `postgresql_server_install’ for cookbook: <wrapper_cookbook>
Chef Development Kit Version: 2.4.17
chef-client version: 13.6.4
delivery version: master (73ebb72a6c42b3d2ff5370c476be800fee7e5427)
berks version: 6.3.1
kitchen version: 1.19.2
inspec version: 1.45.13

In my metadata.rb file i do have depends on postgressql. Any help is appreciated.

NM the docs on github are updated for 7.0 but the cookbook from supermarket is only at 6.1.1.
