The problem is with the second INSERT statement - I cannot use the id.Only those constraints are shown for which the current user has write access to the referencing table (by way of being the owner or having some privilege other than SELECT ). 0001_initial -> this migration file worked successfully long ago The view referentialconstraints contains all referential (foreign key) constraints in the current database. ![]() In this migration, I changed the primary key(id) field in the " app_user_user" table from int to bigint I made no changes to Django's standard tables " app_user_user_groups" and " app_user_user_user_permissions".
