While working on connection pooling for postgres I ran into the following
regression (since
https://github.com/django/django/commit/8fb0be3500cc7519a56985b1b6f415d75ac6fedb
):
{{{
from django.db import connection
from django.test import TestCase
class Test(TestCase):
def test_something(self):
new_connection = connection.copy("asd")
with new_connection.cursor() as cursor:
print(cursor.execute("SELECT 1").fetchall())
}}}
On 5.0 this works fine, on main this fails with:
> django.test.testcases.DatabaseOperationForbidden: Database threaded
connections to 'asd' are not allowed in this test. Add 'asd' to
test_regression.Test.databases to ensure proper test isolation and silence
this failure.
I cannot really add this to `databases` since this is a dynamically
created database. I am opening this as release blocker so it doesn't get
lost (I might be holding it wrong though)
