- Fixed a regression in 1.8.8 causing incorrect index handling in migrations on PostgreSQL when adding `db_index=True` or `unique=True` to a `CharField` or `TextField` that already had the other specified, or when removing one of them from a field that had both, or when adding `unique=True` to a field already listed in `unique_together` (#26034).
