You don't use lo_import directly for that.  There is an example program
included with psycopg that shows the right syntax to insert a file.  For
psycopg1, see bytea.py ; for psycopg2 look at binary.py

Just so you know, the commands starting with \ like \lo_import are
specific to the psql client.  None of those will work if you use another
tool to connect.
