    /*
    The @rowcount_only param is overloaded for shiloh release due to backward compatibility concerns.
    In shiloh, the checksum functionality has changed.   So 7.0 subscribers will have the old checksum
    routines, which generate different CRC values, and do not have functionality for vertical partitions,
    or logical table structures where column offsets differ (due to ALTER TABLEs that DROP and ADD columns).

    In 7.0, this was a bit column.  0 meant do not do just a rowcount - do a checksum.  1 meant just do a
    rowcount.

    For Shiloh, this parameter is changed to a smallint with these options:
    0 - Do a 7.0 compatible checksum
    1 - Do a rowcount check only
    2 - Use new Shiloh checksum functionality.  Note that because 7.0 subscribers will
    take this parameter as a bit type, not a smallint, it will be interpreted as simply
    ON.  That means that passing a 2, and having a 7.0 subscriber, will result in the 7.0
    subscriber doing only rowcount validation.   The Shiloh subscribers will do both
    rowcount and checksum.  If you want 7.0 subscribers to do checksum validation, use
    the value of 0 for this parameter.   Shiloh subscribers can do the 7.0 compatible
    checksum, but that checksum has the same 7.0 limitations for vertical partitions
    and differences in physical table structure.)
