The \< and \> characters mark word boundaries which are a GNU regex extension. Since you appear to be on a Linux system that has GNU sed, this should work. In regular expressions, the . character is special (it means "any character" ) and therefore it needs to be escaped with a backslash to use its literal meaning.

LEARN ABOUT SUSE
listen
LISTEN(7) SQL Commands LISTEN(7)NAME
LISTEN - listen for a notification
SYNOPSIS
LISTEN name
DESCRIPTION
LISTEN registers the current session as a listener on the notification condition name. If the current session is already registered as a
listener for this notification condition, nothing is done.
Whenever the command NOTIFY name is invoked, either by this session or another one connected to the same database, all the sessions cur-
rently listening on that notification condition are notified, and each will in turn notify its connected client application. See the dis-
cussion of NOTIFY for more information.
A session can be unregistered for a given notify condition with the UNLISTEN command. A session's listen registrations are automatically
cleared when the session ends.
The method a client application must use to detect notification events depends on which PostgreSQL application programming interface it
uses. With the libpq library, the application issues LISTEN as an ordinary SQL command, and then must periodically call the function PQno-
tifies to find out whether any notification events have been received. Other interfaces such as libpgtcl provide higher-level methods for
handling notify events; indeed, with libpgtcl the application programmer should not even issue LISTEN or UNLISTEN directly. See the docu-
mentation for the interface you are using for more details.
NOTIFY [notify(7)] contains a more extensive discussion of the use of LISTEN and NOTIFY.
PARAMETERS
name Name of a notify condition (any identifier).
EXAMPLES
Configure and execute a listen/notify sequence from psql:
LISTEN virtual;
NOTIFY virtual;
Asynchronous notification "virtual" received from server process with PID 8448.
COMPATIBILITY
There is no LISTEN statement in the SQL standard.
