-- This migration will fail with any records in the db. If you are working with a normal server, you

-- to set all existing db records to the specified guild. A mixed / fucked up db sceneario will
-- require you to manually edit the db and ensure `guild` is set in `memes`, `invocation_records`,
-- and `tombstones`.
