Well, unless server generated keys can only be numeric (increment by
one, i.e predictable) (which is the only kind I've used), then I think
it's essential that we somehow can get each of the generated keys.

As for Sun/others, I do know that this feature works well in other
dbms's - every one I've used supports it, and with multiple rows
inserted. But I've only ever used numeric server generated keys so I
don't know if other types are supported on those DBs.

As an aside, how do PG jdbc users get the server generated keys? Or does
everyone use some kind of UUID system (which I think is generally
regarded as detrimental to indexes/memory under high load and large DB
sizes - compared to int/bigint)? Or do PG users using some standard or
server-specific (RETURNING) SQL clause?
