So, the contributor guidelines page about unit tests mentions running database specific tests:
https://docs.djangoproject.com/en/2.1/internals/contributing/writing-code/unit-tests/#testing-other-python-versions-and-database-backends I am working on ticket 29984, and it seems to me that since the TruncDay is attempting to cast to the timezone on the database level, it is working, and its job is done. So, the fix should be at the backend level, and the ticket provides one for Postgres. Following the unit test advice, I created a settings file. But not using my Postgresql admin user. I get the following errors: psycopg2.ProgrammingError: permission denied to create extension "btree_gin" HINT: Must be superuser to create this extension. I'm not going to do that - do you have any list of required extensions? -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
