On databases that support transactions with statements that change the schema
(such as PostgreSQL or SQLite3), migrations are wrapped in a transaction. If the
database does not support this (for example MySQL) then when a migration fails
the parts of it that succeeded will not be rolled back. You will have to unpick

the changes that were made by hand.
