/* Rules:
- Never use models in the upgrade process - never ever!
- Use the provided addColumn, alterColumn, dropPrimaryKey etc. functions where applicable - they ensure cross-DB compatibility
- Never use foreign keys
- Use only the field types listed here:

    pk: auto-incremental primary key type (“int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY”).
    string: string type (“varchar(255)”).
    text: a long string type (“text”) - MySQL: max size 64kb - Postgres: unlimited - MSSQL: max size 2.1GB 
    mediumtext: a long string type (“text”) - MySQL: max size 16MB - Postgres: unlimited - MSSQL: max size 2.1GB
    longtext: a long string type (“text”) - MySQL: max size 2.1 GB - Postgres: unlimited - MSSQL: max size 2.1GB
    integer: integer type (“int(11)”).
    boolean: boolean type (“tinyint(1)”).
    float: float number type (“float”).
    decimal: decimal number type (“decimal”).
    datetime: datetime type (“datetime”).
    time: time type (“time”).
    date: date type (“date”).
    binary: binary data type (“blob”).

    These are case-sensitive - only use lowercase!
- If you want to use database functions make sure they exist on all three supported database types
- Always prefix key names by using curly brackets {{ }}
