Yeah, it also surprised me a bit. Having a NULL instead of '' in \d* is
IMO not that dramatic, but things get different when accessing the
catalog directly, e.g.
postgres=# \pset null '(null)'
postgres=# CREATE TABLE t (id int);
CREATE TABLE
postgres=# COMMENT ON TABLE t IS '';
COMMENT
postgres=# SELECT obj_description('t'::regclass, 'pg_class');
obj_description
-----------------
(null)
