Or a PK that's not an integer? Or no PK at all?
There's not likely to be any interest in hotwiring INSERT to return
a different command tag than it does now; that would break too much
existing code. There has been some talk of inventing an "INSERT
... RETURNING ..." syntax extension that would return whatever
expressions you cared to compute from inserted rows --- but in the form
of a SELECT result, not by trying to squeeze it into a command tag.
I think the last discussion of this was a year or so back in pg-hackers.
