Could copy be extended to support a more SQL-friendly syntax. like

COPY tablename FROM VALUES(
 (x1,y1,z1),
 (x2,y2,z2),
 (x3,y3,z3)
);

The main reason I have not used COPY very much is it's non-SQL syntax 
for field values.

Extending the COPY command would probably be much easier than speeding up
INSERTS.
