Are you sure the backend is reading directly from the file, and not
through psql? (\copy, or COPY FROM STDIN, would go through psql.)
But even so that seems awfully high, considering how little work psql
has to do compared to the backend. Has anyone ever profiled psql doing
this sort of thing? I know I've spent all my time looking at the
backend ...
