+1.  In fact, I don't even see why the "unlogged" property needs to be
a schema property.  I think you could just add a table reloption.
(There are some possible foot-gun scenarios if the option were changed
subsequent to table creation, so we'd either need to decide how to
deal with those, or decide not to allow it.)
