I would also love to have copy support (again) in the driver, but
did you actually test that it would speed up your inserts?
You could save your 4m rows into a txt file and then
something like
cat file.out | psql -d db -c "copy table from stdin delimiter '\t';"
and then you would know if copy would really speed your
inserts up.
