 Ideally used in conjunction with my Alpine Linux
 playbook, though it shouldn't be hard to adapt it to
 other systems.
+
+
+Securing your postgres installation should go as follows:
+
+```
+root@alpine-dev /root # psql -U postgres  
+psql (11.5)
+Type "help" for help.
+
+postgres=# \password
+Enter new password: 
+Enter it again: 
+postgres=# \q
+root@alpine-dev /root # sv down postgres
+root@alpine-dev /root # sed -i.bak -e's/trust$/md5/g' /var/postgres/pg_hba.conf
+```
+
+Ideally add the password to your `~/.pgpass` if you're going to do
+backups from cron or similar. This can be done by defining `postgres_pgpass`
+as found  commented out in `defaults/main.yml`
