Something like:
CREATE OR REPLACE FUNCTION bytea_to_int8( ba BYTEA, OUT res INT8 )
LANGUAGE plpgsql STRICT
AS $BODY$
DECLARE
i INT;
BEGIN
res := 0;
FOR i IN 0 .. 7 LOOP
res := 256*res + get_byte( ba,i );
END LOOP;
END;
$BODY$;
gives me back errors (ERROR: bigint out of range) because of overflow
at step no.7
