Hello,
I ran into an intermittent migration issue on Django 4.x and PostgreSQL.
The migrations work fine on Django 3.2.x, but intermittently fail on
Django 4.x with the following exception:
django.db.utils.ProgrammingError: constraint
"polls_questioncontribution_base_question_id_25bfb2a8_fk" for relation
"polls_questioncontribution" already exists
I made a small demo repo to show the problem:
https://github.com/bcail/migration_error. I put the sqlmigrate output
from Django 3.2 and Django 4 in the repo, and it looks like Django 4
(sometimes) creates duplicate SQL statements.
I also ran git bisect on the Django code, and it looks like the problem
starts showing up with this commit:
https://github.com/django/django/commit/3d9040a50b160f8b4bb580e09f4120d4979fe29e.
Should I open a Django issue, or is there something else going on here?
Thanks,
-Ben
