Hmm. Temporary relations are a whole different story.
It would be nice if updates on temp relations never got WAL-logged at
all, but I'm not sure how feasible that is. Right now we don't really
distinguish temp relations from ordinary ones --- in particular, they
have pg_class entries, which surely will get WAL-logged even if we
persuade the buffer manager not to do it for the data pages. Is that
a problem? Not sure.
