BTW, that was on a local Unix-socket connection. On a network
connection, COPY would have a huge advantage because (a) it could
transfer multiple rows per packet, if your rows are not too long,
and (b) you would not have to wait for the server to answer back
before sending the next packet.
In theory you could pipeline INSERT commands like that too, but not
with libpq.
