   pg_tty() returns the TTY name that server
   side debugging output is sent to on the given PostgreSQL
   connection resource.
  
Note:
pg_tty() is obsolete, since the server no longer pays attention to the TTY setting, but the function remains for backwards compatibility.

   A string containing the debug TTY of 
   the connection, or FALSE on error.
