Yeah. It was asserted in the earlier thread that other vendors implement
this feature as "return the pkey", but that seems to conflict with the
plain language of the JDBC spec: generated columns are an entirely
different thing than primary key columns. So really what I'd like to see
is some work on surveying other implementations to confirm exactly what
behavior they implement. If we're to go against what the spec seems to
say, I want to see a whole lot of evidence that other people do it
consistently in a different way.
