For prepared queries you're absolutely correct.  It's also true that
it's the recommended approach for large numbers of inserts.  If the
network delay is more of a problem than the processing speed then it
might make sense.

It does seem to me that with multi-value insert we might consider
changes to libpq to be able to use multi-value prepared inserts...  Or
it might be interesting to see the performance of non-prepared
multi-value inserts vs. prepared statements.

    Thanks,
