    NAME

    UNLISTEN - stop listening for a notification
    

     

    SYNOPSIS

    UNLISTEN { name | * }
    
    
     

    DESCRIPTION

    UNLISTEN is used to remove an existing registration for NOTIFY events. UNLISTEN cancels any existing registration of the current PostgreSQL session as a listener on the notification name. The special wildcard * cancels all listener registrations for the current session.

    NOTIFY [notify(7)] contains a more extensive discussion of the use of LISTEN and NOTIFY.  

    PARAMETERS

    name
    Name of a notification (any identifier).
    *
    All current listen registrations for this session are cleared.
     

    NOTES

    You may unlisten something you were not listening for; no warning or error will appear.

    At the end of each session, UNLISTEN * is automatically executed.  

    EXAMPLES

    To make a registration:

    LISTEN virtual;
    NOTIFY virtual;
    Asynchronous notification "virtual" received from server process with PID 8448.
    
    

    Once UNLISTEN has been executed, further NOTIFY commands will be ignored:

    UNLISTEN virtual;
    NOTIFY virtual;
    -- no NOTIFY event is received
    
    
     

    COMPATIBILITY

    There is no UNLISTEN command in the SQL standard.

    LISTEN [listen(7)], NOTIFY [notify(l)]
