 No special requirements; note that this role requires root access, so either run it in a playbook with a global `become: yes`, or invoke the role in your playbook like:
 
+```yaml
 - hosts: database
   roles:
     - role: geerlingguy.postgresql
       become: yes
-
+```
 ## Role Variables
 
 Available variables are listed below, along with default values (see `defaults/main.yml`):
 
+```yaml
 postgresql_enablerepo: ""
-
+```
 (RHEL/CentOS only) You can set a repo to use for the PostgreSQL installation by passing it in here.
 
+```yaml
 postgresql_restarted_state: "restarted"
+```
 
 Set the state of the service when configuration changes are made. Recommended values are `restarted` or `reloaded`.
 
+```yaml
 postgresql_python_library: python-psycopg2
+```
 
 Library used by Ansible to communicate with PostgreSQL. If you are using Python 3 (e.g. set via `ansible_python_interpreter`), you should change this to `python3-psycopg2`.
 
+```yaml
 postgresql_user: postgres
 postgresql_group: postgres
+```
 
 The user and group under which PostgreSQL will run.
 
+```yaml
 postgresql_unix_socket_directories:
   - /var/run/postgresql
+```
 
 The directories (usually one, but can be multiple) where PostgreSQL's socket will be created.
 
+```yaml
 postgresql_service_state: started
 postgresql_service_enabled: true
+```
 
 Control the state of the postgresql service and whether it should start at boot time.
 
+```yaml
 postgresql_global_config_options:
   - option: unix_socket_directories
     value: '{{ postgresql_unix_socket_directories | join(",") }}'
   - option: log_directory
     value: 'log'
+```
 Global configuration options that will be set in `postgresql.conf`.
 For PostgreSQL versions older than 9.3 you need to at least override this variable and set the `option` to `unix_socket_directory`.
 If you override the value of `option: log_directory` with another path, relative or absolute, then this role will create it for you.

 postgresql_hba_entries:
   - { type: local, database: all, user: postgres, auth_method: peer }
