To add descriptions:

COMMENT ON TABLE foo IS 'Some Text Here';

To drop the descriptions:

COMMENT ON TABLE foo IS NULL;

\h COMMENT should give yo all the details. Naturally, the
comments are dropped when the associated object is dropped. You
can comment on any PostgreSQL object and the comments are dumped
with pg_dump.

Hope that helps,
