This PR is for #MPP-3746.

How to test:

1. pip install -r requirements.txt
2. Be sure that your postgresql is logging to a directory and log file you can see (I made the changes in https://stackoverflow.com/q/722221 and restarted my postgresql server)
3. python manage.py runserver
4. Sign in at http://127.0.0.1:8000/
5. Go to http://127.0.0.1:8000/api/v1/relayaddresses/?format=json
6. Open your postgresql log file from step 2
   • You should see strings like this appended to the SQL SELECT statement logs: /*controller='relayaddress-list',framework='django%3A4.2.11',route='api/v1/relayaddresses/%24'*/

Thanks @groovecoder, looks good to me!

I used:

brew services stop postgresql@14
/opt/homebrew/opt/postgresql@14/bin/postgres -D /opt/homebrew/var/postgresql@14 -c log_statement=all

and got logs like:
