    Fix misplaced comma
    
    This resulted in the SHOW HELP response message to be misformatted.
    In older PostgreSQL versions, the intended last line would just be cut
    off silently, but in PostgreSQL 15 libpq, an error message
    
        message contents do not agree with length in message type "N"
    
    is shown, making the test_show test fail.
    
    addresses part of #769
