portal,however it would be much more useful if we received the CommandStatus after the insert was completed and before

I believe if RETURNING clause is use, the protocol-level behaviour of
INSERT is expected to match that of SELECT. If the SELECT command
behaves like that (resultset followed by CommandStatus), then I'd say
the INSERT RETURNING is behaving as expected.
