hhmmmmm instanceof sort of looks bad though in this case its perfectly
defensible. My suggestion was to have

 ClassPersister.isUsingNativeKeyGeneration()

or something. But then you would need to set that up in the first place
which would involve doing either an instanceof or equivalent anyway....
How about if we use instanceof in the constructor of ClassPersister
where its nice and hidden away and no-one will notice it ;)

I'm not quite joking; I'd prefer "expedient" things in any class other
than RelationalDatabaseSession. Yeah, I know I wouldn't be able to defend
this if pressed  .... whatever ..... just stick an instanceof wherever
you think is right.....

I'm rambling today....

Very Badly.

Actually there are large objects but theres some wierd way of using them
I don't understand....

Also theres a varbinary type, of course.

Thats all good. I'm not at all perturbed by that (anyway Dialect is an
abstract class, not an interface, so we can do more with it).
