database connection isn't set to UTC

[Janet Jiang]

Hi all,

I was pushing a new project to Heroku. I was able to open the app and go to the demo page, but when I clicked on the links for testing, I got the following error. Has anybody seen this before? Thanks!

After a lot of search, I think the problem is described here:

https://stackoverflow.com/questions/68024060/assertionerror-database-connection-isnt-set-to-utc

I followed the instructions to put "psycopg2>=2.8,<2.9" in my requirements file and it solved my problem.

I've fixed this issue in the latest 3.x release (it doesn't affect 5.x).
