Hi everyone, I have the same problem of this ticket from django trac: https://code.djangoproject.com/ticket/7783
The PostgreSQL database introspection does not detect NULL columns, cursor.description does not return the null_ok field, so database introspection does not add null=True to column definitions. The is_nullable column in information_schema.columns does contain this information, however. A patch was subimitted, but i can't apply this 'cause the version of django that's the patch was appliend is different to 1.3 (the version i use). Somebody knows what version of django this patch is applied? Or a other way to solve this problem?
