If the managed system is EL7 and has LANG=C.UTF-8, it fails.

This includes when the Vagrant host (Github Actions CI) has LANG=C.UTF-8, it bleeds over to the managed guest by Vagrant design:

I have an incomplete fix here:

(It's not working properly, LANG is still C.UTF-8 in the postgresql role when I added debug statements to said role.)

I will workaround this on Github Actions CI by changing LANG on the host.

The permanent fix will be to just upgrade CentOS 7 systems to PostgreSQL 10 instead.
