Oh I see.
But we still can comment on indexed columns like following on 8.3.7,
is it unsupported feature?
create table person (social_no integer, name text, age integer, uri
text, PRIMARY KEY  (social_no));create index person_age on person using BTREE (age);comment on column person_age.age IS
'helloindex person_age.age'; 

And we can find the comment in pg_description table.

> Do we support comments on composite types

If we do, I will also write a patch for it.

Cheers.
