Ticket #32485 – Description
v1 v2 1 For https://github.com/django/django/blob/master/django/db/backends/postgresql/operations.py#L103 1 [https://github.com/django/django/blob/master/django/db/backends/postgresql/operations.py#L103] 2 2 3 3 There are 2 major disadvantages of using UPPER instead of buttonhole in Django ORM "icontains" operator. First of all, I would like to talk about the performance problem. If you add an expression to an index set for the "like" operator, index will not be used.
