Doing bulk inserts via host arrays is not possible AFAICT.
I posted a similar request in February 2003.
See
http://archives.postgresql.org/pgsql-interfaces/2003-02/msg00091.php

BTW, I don't see how a bulk update could be done.

There is a way to use COPY programmatically via libpq:

something like ...

PQexec("COPY xxx FROM stdin");
for (...)
{
sprintf(buf, "%d\t%d\t...\n",
values[0], values[1], ... values[n]);
PQputline(conn, buf);
}
PQputline(conn, "\\.\n");
PQendcopy(conn);
