Loop through all user tables and insert row in each - postgresql

Question

for some reason I just can not figure this out. I have a seperate schema in PostgreSQL for notification related tables for each user connected to the server. My plan is to have each user create a TEMP table to receive extra notification info from since Xojo doesn't support PostgreSQL payloads.
I feel like I'm starting to get close so I'll just post my code that is in my trigger function.
DECLARE
my_table RECORD;
BEGIN
FOR my_table IN
SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'information_schema'
LOOP
INSERT INTO my_table.table_name (effected_row_id)
VALUES (NEW.effected_row_id);
END LOOP;
END;
Tell me if I'm wrong, but I believe my main problem is figuring out how to use the table name returned from the SELECT statement in the INSERT statement.
EDIT:
This is my current trigger function
-- Function: notification.my_insert_trigger_function()
-- DROP FUNCTION notification.my_insert_trigger_function();
CREATE OR REPLACE FUNCTION notification.my_insert_trigger_function()
RETURNS trigger AS
$BODY$DECLARE
my_table RECORD;
BEGIN
FOR my_table IN
SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'notification' AND table_name <> 'notification_global' AND table_name <> 'switcher'
LOOP
EXECUTE(FORMAT($f$
INSERT INTO %s (effected_row_username)
VALUES (%s);
$f$, 'notification.' || my_table.table_name, NEW.effected_row_username));
END LOOP;
RETURN new;
END;$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION notification.my_insert_trigger_function()
OWNER TO serveradmin;

You need to use dynamic commands in your trigger function.
The funcion format() is often very helpful.
DECLARE
my_table RECORD;
BEGIN
FOR my_table IN
SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'information_schema'
LOOP
EXECUTE(FORMAT($f$
INSERT INTO %s (effected_row_id)
VALUES (%s);
$f$, my_table.tablename, NEW.effected_row_id));
END LOOP;
END;
