AssertionError: database connection isn’t set to UTC
A recent update to psycopg2 version 2.9 is causing this issue
Psycopg 2.9 changed the value passed to tzinfo_factory from an int to a timedelta. Django 2.2 (possibly newer but I’m on 2.2) has a check for offset == 0 and since timedelta(0) != 0 it goes boom.
A current solution would be to downgradepsycopg2 (oupsycopg2-binary if you are using the stand-alone package) below 2.9 (e.g.psycopg2>=2.8,<2.9) in your requirements file.
For instance, you can downgrade to2.8.6 using:
pip install psycopg2==2.8.6ou
pip install psycopg2-binary==2.8.6If you’re using poetry, you can dopoetry add psycopg2@2.8.6 to fix your version to2.8.6.
