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 Post- greSQL 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 can 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.
