fix(dev): psycopg2-binary 2.9.1 does not work with Django 2.2

For the incompatibility issue with Django visit [this issue][incompatible],

In this PR, we're going to downgrade to the compatible 2.8.6 version (thus, matching
the Python 3.6 version), removing the need to install `postgresql` (this means partially
reverting #28607) and instead installing a wheel I built on my machine that I have stored
in GC storage.

Fixes #28958

[incompatible]: psycopg/psycopg2#1293
