Axel and Sergi: thanks for both your replies - please see what I have found.
First, looked for roles:
 
\du
                             List of roles
 Role name |                   Attributes                   | Member of
-----------+------------------------------------------------+-----------
 postgres  | Superuser, Create role, Create DB, Replication | {}
 tryton    | Create DB                                      | {}

 Then, check for pg_hba.conf, but cannot find it in /var/lib:

ls
apt        dpkg             libreoffice  postgresql      systemd      vim
cloud      emacsen-common   logrotate    python          tryton       
xml-core
container  initramfs-tools  man-db       python-support  ucf
dbus       initscripts      misc         sgml-base       update-rc.d
dhcp       insserv          pam          sudo            urandom

I am checking out Tryton project as user/beginner, so explain like I'm 5 if 
you need to.
Regardless, I'm committed to figure it out so any additional guidance is 
greatly appreciated.
