Hello.

When I executed the following program which was in the manual of postgres

I received the message, Error: Unexpected identifier: ?|A@.
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

But, on another host of postgres this program was executed successfully.

Please, Let me know what problems are there.

Thanks in advance.

Yeong-jeong Jeong.
