This sound great. Unfortunately I can't extract the whole stacktrace.
I only get the lines below psycopg, not the above (lines of the callers).

Here is my code:

class MyAppConfig(AppConfig):

def ready(self):
connection_created.connect(connection_created_check_for_notice_in_connection)

class ConnectionNoticeList(object):
def append(self, message):
if not 'some_magic_of_db_trigger' in message:
return
logger.warn('%s %s' % (message, ''.join(traceback.format_stack())))

def connection_created_check_for_notice_in_connection(sender, connection, **kwargs):
connection.connection.notices=ConnectionNoticeList()

I see this in the logs:

'NOTICE: some_magic_of_db_trigger: 17909
File "/snap/pycharm-community/128/helpers/pycharm/_jb_pytest_runner....ork/foo/apps.py", line 47, in append
logger.warn(\'%s %s\' % (message, \'\'.join(traceback.format_stack())))
'

traceback.format_stack() inside ConnectionNoticeList.append() extracts not the callers.

Is there a way to get the callers lines?
