Yeah. There were once multiple types of large objects, and I suppose
the mode argument told lo_creat which kind to create. I have no idea
how the read/write bits got included into that --- it doesn't make any
sense. As of PG 8.1, lo_creat just ignores the mode argument. We can't
delete the argument though without causing a lot of compatibility
headaches.
