Or just always do a \pset null. For me printing NULL the same as an
empty string is just as confusing in normal tables, so that's the first
line in my ~/.psqlrc. YMMV, of course.

But I guess the point is that people who do \pset null expect to be able
to distinguish '' and NULL visually and might be surprised if that
doesn't work everywhere, while people who don't \pset null know that ''
and NULL are visually indistinguishable and that they may need some
other way to distinguish them if the difference matters.

So +1 for me fixing \dp to honor "\pset null".
