So I'm from the camp that advocates the use of surrogate
    keys for every table reqardless if a candidate keys already
    exists.

    There are two tables that don't use them:

        TURBINE_ROLE_PERMISSION
        TURBINE_USER_GROUP_ROLE

    And another table, TURBINE_JOBENTRY, whose key, JOBID, should
    be made to be autoincrement.

    Does anyone object if we/I update the three tables?  The big win
    for using surrogate keys is that you add/change/delete columns
    without affecting the relational intregrity.
