psycopg2.errors.UndefinedColumn: column "public" does not exist

[rahulkp220]

Using Django==3.0.4 and Python 3.7.3
I am ok for the issue to be closed if this app doesn't support the versions of django or python I am currently using.

The above exception was the direct cause of the following exception:

I'm getting this same error with Python 3.10 and Django 4.0.3 when adding a column.

The first migration was applied before? Because in your log the migrations are starting from the second file.
