To use the most modern version of Postgres software we need to add postgresql repository. Edit /etc/apt/sources.list or create /etc/apt/sources.list.d/pgdg.list and add there a line: deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main Then import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Install a new version of PostgreSQL server.

Once the Debian upgrade finished, I used dpkg-query -l postgresql* to check which versions of postgres I have installed.

TL;DR

9.4 -> 9.5:

sudo pg_dropcluster 9.5 main --stop
sudo service postgresql stop
sudo pg_upgradecluster -m upgrade -k 9.4 main
sudo su postgres -c "/usr/lib/postgresql/9.5/bin/vacuumdb --all --analyze-in-stages"
sudo pg_dropcluster 9.4 main
