change output of \dp

Hi,

I just noticed that \dp outputs "Table" to indicate relations (tables, sequences and views) instead of "Relation" or
"Name".This patch just correct it, using "Name"  and attaching its "Type". 

Without the patch:

teste=# \d
         List of relations
 Schema |  Name  |   Type   | Owner
--------+--------+----------+-------
 public | ab     | sequence | euler
 public | foo    | table    | euler
 public | foobar | view     | euler
 public | teste  | table    | euler
(4 rows)

teste=# \dp
                  Access privileges for database "teste"
 Schema | Table  |              Access privileges
--------+--------+---------------------------------------------
 public | ab     | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
 public | foo    | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
 public | foobar |
 public | teste  | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
(4 rows)

And with the patch:

teste=# \dp
                  Access privileges for database "teste"
 Schema |  Name  |   Type   |              Access privileges
--------+--------+----------+---------------------------------------------
 public | ab     | sequence | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
 public | foo    | table    | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
 public | foobar | view     |
 public | teste  | table    | {euler=a*r*w*d*R*x*t*/euler,teste=ar/euler}
(4 rows)

Please apply it under HEAD, and if it's convenient, put it under 7_4 Branch.

Regards,
