    11Replying to [comment:1 Mariusz Felisiak]:
    2 > Thanks for the report, however the builtin `django.db.backends.postgresql` backend (on Python `3.9.0+` and `3.8.5`) raises `Connection refused` for me (as expected):
    3 > {{{
    4 > django.db.utils.OperationalError: could not connect to server: Connection refused
    5 >         Is the server running on host "localhost" (127.0.0.1) and accepting
    6 >         TCP/IP connections on port 5432?
    7 > }}}

    2619I found a problem. The problem is in [these lines](https://github.com/django/django/blob/f9cfd346f0222d86bfbac26ef5455806965bae6b/django/db/backends/postgresql/base.py#L324-L325). If I have one connection and test expression in if return false then function just return without reraise exception. And `contextmanager` raises error `RuntimeError: generator didn't yield`
