1. Psql postgres, run "\d" and find relations in database.
{code}
psql postgres
psql (8.2.15)
Type "help" for help.

postgres=# \d
                      List of relations
 Schema |      Name      | Type  |    Owner     |   Storage
--------+----------------+-------+--------------+-------------
 public | sales1         | table | wangchunling | append only
 public | sales1_1_prt_1 | table | wangchunling | append only
 public | sales1_1_prt_2 | table | wangchunling | append only
 public | t              | table | wangchunling | append only
 public | tv             | view  | wangchunling | none
(5 rows)

{code}
2. Quit the session and disconnect the network. Then psql postgres, run "\d" and get expected
error.
{code}
$ psql postgres
psql (8.2.15)
Type "help" for help.
