django asyncio postgresql Python

I'm trying to debug I've been working on this all day and I'm currently working with Django 4.2 and trying to implement asynchronous views to improve the performance of my web application... However, I'm working with persistent `django.db.utils.InterfaceError: connection already closed` errors when executing async database queries. The code below demonstrates the scenario: ```python from django.shortcuts import render from django.http import JsonResponse from myapp.models import MyModel from asgiref.sync import sync_to_async async def my_async_view(request): try: results = await sync_to_async(MyModel.objects.all)() data = [result.to_dict() for result in results] return JsonResponse(data, safe=False) except Exception as e: return JsonResponse({'behavior': str(e)}, status=500) ``` I've tried using `sync_to_async` to wrap the database call, but it seems like the connection to the database is intermittently dropping or closing after some requests. I've also increased the connection timeout settings in my `settings.py`, but the question continues. The database is PostgreSQL 14, and I'm using `psycopg2` as the database adapter. I've checked the database logs and found a few hints about connection limits being reached, but I believe my max connections setting is suitable for my current load. Has anyone else faced similar issues with async views in Django, or does anyone have suggestions on how to manage database connections more effectively in this context? Any advice would be appreciated! Any help would be greatly appreciated! This is happening in both development and production on Ubuntu 20.04. I'm working on a mobile app that needs to handle this. Could someone point me to the right documentation? Am I missing something obvious?
