DatabaseError when changing username as admin
I get an error (I get an email from my site) when I'm trying to change some users name:
DatabaseError: record "new" is not assigned yet
DETAIL: The tuple structure of a not-yet-assigned record is indeterminate.
CONTEXT: PL/pgSQL function "group_membership_tsv_update_handler" line 6 at assignment
python manage.py migrate
python manage.py collectstatic
don't solve the problem.
