good to hear that progress is made on that front!

Well the postgresql.org infrastructure is running debian stretch and all
our current django applications are on django 1.8.18 in a custom (but
internally packaged) virtualenv - we have not yet decided on what
version we will move to next (because 1.8 will be EoS'd in April) but it
will likely be an LTS version.

In general we very heavily rely on packaged software for maintainability
so I would advise to stay away from versions of software that are not
packaged in stretch (or debian in general) - for postgresql itself we
use apt.postgresql.org so any version that is available there should be
fine.

Also note that you application should be designed to not require any
root-user interaction because we usually do not hand out that kind of
privilege.
