How can I add a comment to a table, function, etc. that will should up in a
/dd comment in psql?

joe=> \d pg_description

Table    = pg_description
+----------------------------------+----------------------------------+-------+
|              Field               |              Type                | Length|
+----------------------------------+----------------------------------+-------+
| objoid                           | oid                              |     4 |
| description                      | text                             |   var |
+----------------------------------+----------------------------------+-------+
To add your own description you have to know the oid of your table,function, etc
and then assign this valuo to pg_description.objoid and your description to pg_description.description.
Take a look:

joe=> select relname,oid from pg_class where relname='btmm';
relname|   oid
-------+------
btmm   |190177
(1 row)

joe=> \dd btmm
description
--------------
no description
(1 row)

joe=> insert into pg_description values(190177,'a minha tabela');
INSERT 226304 1

joe=> \dd btmm
description
--------------
a minha tabela
(1 row)
