That worked.  I used the Docker image postgres:12-beta2 to bring up the
server.

One issue that I kept having was error messages like chown: changing
ownership of '...': Permission denied.  That turned out to be an SELinux
issue on the CentOS machine.  I have set SELinux to permissive mode
temporarily to bring the server up.  Sharing it here for the next guy
(most likely my future self).

Thanks again,
