Using a loop on a package module via squash_actions

The use of squash_actions to invoke a package module, such as “yum”, to only invoke the module once is deprecated, and will be removed in Ansible 2.11.

Instead of relying on implicit squashing, tasks should instead supply the list directly to the name, pkg or package parameter of the module. This functionality has been supported in most modules since Ansible 2.3.

OLD In Ansible 2.6 (and earlier) the following task would invoke the “yum” module only 1 time to install multiple packages

- name: install PostgreSQL
  yum:
   name:
     - postgresql94-server
     - postgresql94-contrib
     - pg_repack94
   state: latest
