Are you sure about that? We're using it right now on several tables with
multi-column primary keys with no problems.
There used to be a problem with tables that had _no_ primary key, but the
developer (Steve Singer IIRC) fixed that, at least in so far as it no longer
crashes. I don't know if it actually replicates those tables since I got
primary keys added to all our *ahem* unnormalized tables.
