django with postgresql is incompatible with pypy

[Владимир]

When using django 4.2 and higher with pypy, it is impossible to use postgresql. Versions below require psycopg2cffi, and perfectly work with it, but once I switched to django.4.2, I faced following exception:

File "/opt/pypy/lib/pypy3.10/site-packages/django/db/backends/postgresql/base.py", line 47, in <module>

from .psycopg_any import IsolationLevel, is_psycopg3 # NOQA isort:skip

File "/opt/pypy/lib/pypy3.10/site-packages/django/db/backends/postgresql/psycopg_any.py", line 77, in <module>

from psycopg2 import errors, extensions, sql # NOQA

Hello Владимир, thank you for your report.

Support for Django using PyPy3.10 was confirmed when #34986 was fixed. See scheduled tests runs showing passing runs for latest Django, Postgresql and PyPy3.10:

I'll be closing this issue as invalid, but if you are still having problems after trying latest Django and PyPy3.10, you can reach out to any of the user support channels from ​this link.
