A Django backend for PostgreSQL using Psycopg > 2

The backend passes the entire Django test suite, but it needs a few modifications to Django and to its test suite. These changes will be proposed to the Django project in a series of merge requests. A writeup explains the changes in more details.

The modifications required (targeting the main branch at the time of writing) are available in the psycopg3-4.1 Django branch. This is the list of changes.

Approximative instructions

Create and activate a virtualenv any way you like:

python3 -m venv .venv
source .venv/bin/activate

Install Django, from a branch supporting Psycopg 3. Clone the repos to get the test suite too. Example:

git clone -b psycopg3-4.1 https://github.com/dvarrazzo/django.git
pip install -e ./django

Install Psycopg 3 from the master branch:

git clone https://github.com/psycopg/psycopg.git
pip install -e ./psycopg/psycopg

Install the backend (this project):

pip install -e .

Customise the test config module if necessary:

vim configs/test_psycopg3.py
# hack hack
# :wq

Run the django test suite:

python django/tests/runtests.py --settings=configs.test_psycopg3 -v2 --parallel=1 --noinput

A configs.test_psycopg2 module is also available to run the same tests with psycopg2 and check for regressions.
