OK - Missed that.
I do exactly the same thing with ADOdb in PHP but probably don't hit the
Foreign Key problem because they are handled 'generically' so that we
are not dependent on engine implementation. Code works with most of the
engines supported by ADOdb simply by changing the driver name :)

In theory we can then pump data from any existing database and check for
problems - but that is another story ;)
