I don't think so. I tested in our QA lab in both Oracle 9i and 10g. Only one constraint and only one index. This may be true for other databases (I can verify in all the supported), but even if this is the case, would it cause much harm?

Like "getNotNullStringForPK()" returning "not null"/"" or "needsNotNullInPK()" returning true/false ? What should be the default in Dialect? 

By the way, let me know when you come to Brno. I'm in debt with you :-)
