title: Hibernate Envers rev column data type is Integer
body: <p>I am using Hibernate Envers in my application to store audit trail data, all audit related information are storing in *_AUD table correctly. However, the data type of rev column in all _AUD table is Integer data type. I am expecting a big int data type because the maximum range of integer data type is 2147483647. Is there a way to change the data type to big int?</p>
