Re: Adding error messages to a few slash commands

Sorry, I forgot to attach example usage. Here is how these currently behave:

postgres=> \dT foo
     List of data types
 Schema | Name | Description
--------+------+-------------
(0 rows)

postgres => \du foo
     List of roles
 Role name | Attributes
-----------+------------

postgres => \df foo
                       List of functions
 Schema | Name | Result data type | Argument data types | Type
--------+------+------------------+---------------------+------
(0 rows)

Here is how these look like after this change:

postgres=> \dT foo
Did not find any data type named "foo".
postgres => \df foo
Did not find any function named "foo".
postgres => \du foo
Did not find any role named "foo".

Thanks
