> DdlUtils removes system indexes from the model when reading it from a live 
> database. Due to a bug in that index handling, it might however miss some. 
> For instance if the primary key column is also used in a foreign key, then 
> some databases (e.g. Derby) have two system indexes for it. DdlUtils misses 
> the second one (system index for either pk or fk depending on what's reported 
> first), which causes problems later on (e.g. when altering the database, 
> DdlUtils will try to drop the index which of course fails).
