I use

• Python Version: 3.8
• Django Version: 4.2

ad ENGINE in settings.py is this:

DATABASES = { "default": { "ENGINE": "dj_db_conn_pool.backends.postgis",

Similar to #47, I created a new branch: fix_pg, made some changes to postgis's backend, you can try this branch.

The fix worked, and no longer gives the same error as before. A thousand thanks.
