Why? The man page for psql clearly says:
| \dd[S] [ pattern ]
| Shows the descriptions of objects matching the
| pattern, or of all visible objects if no argu-
| ment is given. But in either case, only objects
| that have a description are listed. By default,

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| dexes, sequences), large objects, rules, and
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| triggers. [...]
^^^^^^^^^
So no comments are shown for constraints or table columns
or ...
