Currently there's no automatic (that is, via ecto) way to rollback a migration.
This is due to a fact that there are no DELETEs in Clickhouse per se: only mutations via ALTER.
Wonder if there's anything that can be done for rollbacks only. Maybe even support DELETEs via ALTER as a general case (that may issue a Logger.warning if used for anything else but rollbacks)?
