Comments on columns?

Are there any plans to have psql support comments on columns? For example,
I would like to be able to add a comment on a column of a table and have \dd
display the table comment in addition to any/all column comments.

Find the oid of the column in pg_attribute, and insert into pg_description.

I did that and it works great. I would like \dd tablename to show the table
comment and its column comments.

Yes, I would like this too, and have considered it. The problem I have
had with system tables is that the oid of the table and columns is
generated at initdb time, and not assigned constant values as the
pg_proc entries are.

I could modify psql to show comments, but I can't figure out how to get
the system tables to show this.

In fact, the TODO list has:

* allow pg_descriptions when creating types, tables, columns, and functions
