Hi y'all,
Django 3.2+ supports "db_collation" [1] for "CharField" and
"TextField" along with migration operations ("CreateCollation()",
"RemoveCollation") and the database function "Collate()" [3]. Moreover
CI fields and the entire "citext" module are discouraged since
PostgreSQL 12 [4] in favor of collations. I think it's time to deprecate
CI fields from the "contrib.postgres" in favor of "CharField" and
"TextField" with case insensitive collations (and remove them in Django
5.0).
Best,
Mariusz
