/* FIRST MIGRATION
 *
 * This migration is special since it takes into account that
 * the database can be setup already but also may not be.
 * Therefore you will find all `CREATE TABLE` statements with
 * a `IF NOT EXISTS`, all `INSERT` with an `IGNORE` and in the
 * downgrade function all `DROP TABLE` with a `IF EXISTS`.
 * This ensures compatibility for existing or non-existing
 * databases.
