The tuple structure of a not-yet-assigned record is indeterminate.

Hi there, i'm new to postgres. I want to create view when adding new row. So
what i've got:

CREATE OR REPLACE FUNCTION add_view() RETURNS trigger AS $$
DECLARE
someint integer;
BEGIN
RAISE NOTICE 'dodajesz nowa lige %', NEW.id;
someint := NEW.id;
RAISE NOTICE 'dodajesz nowa lige %', someint;
CREATE VIEW tabelka AS SELECT * FROM t_matches.someint;
RETURN NULL;
END;
$$ language plpgsql;

CREATE TRIGGER league AFTER insert ON t_leagues FOR STATEMENT EXECUTE
PROCEDURE add_view();

Then in psql I made an query and got error:

league=# INSERT INTO t_leagues (name) VALUES('3liga');
ERROR: record "new" is not assigned yet
DETAIL: The tuple structure of a not-yet-assigned record is indeterminate.
CONTEXT: PL/pgSQL function "add_view" line 4 at RAISE

Whats wrong, I supposed that id is not reserverd at the moment, so what can
I do?

And here is some infos about table

league=# \d t_leagues
Table "public.t_leagues"
Column | Type |
Modifiers

id | integer | not null default
nextval('t_leagues_id_seq'::regclass)

awans | smallint | not null default 0
baraz | smallint | not null default 0
