Please do not cross-post.  One list is enough.

PostgreSQL has that functionality, too.

cww=# CREATE TABLE foo (a INTEGER, b INTEGER);
CREATE TABLE
cww=# COMMENT ON TABLE foo IS 'my comment';
COMMENT
cww=# \d+
               List of relations
  Schema | Name | Type  | Owner | Description
--------+------+-------+-------+-------------
  public | foo  | table | cww   | my comment
(1 row)

COMMENT is well-documented.
