Summary

It looks like something doesn't start up right with postfix in the CentOS 8 environment.

Also... varnish won't install on CentOS with error No package pygpgme available.

Under Vagrant I'm not seeing an issue:

● postgresql.service - PostgreSQL database server
   Loaded: loaded (/usr/lib/systemd/system/postgresql.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2020-07-06 16:47:44 UTC; 6s ago
  Process: 8694 ExecStartPre=/usr/libexec/postgresql-check-db-dir postgresql (code=exited, status=0/SUCCESS)

Er... that's not postfix in the comment above... that's postgres :P

Testing again.
