+-- NOTE(fusion): This file contains index adjustments for the `CharacterDeaths`
+-- table. It is not strictly necessary as there are no modified tables but should
+-- help with queries such as the most recent deaths/kills from a specific character
+-- or overall.
+--  It can be executed automatically as a patch if placed at `sqlite/patches`. For
+-- more details see `sqlite/README.txt`. The changes are already present in the
+-- latest `schema.sql`, so trying to apply them on a newly created database will
+-- result in errors.
