EXECUTE in trigger functions.

Hi,

Is there a way of using EXECUTE in trigger functions to to do
something like:

CREATE OR REPLACE FUNCTION insert_trigger()
RETURNS trigger AS
$BODY$
BEGIN
EXECUTE('INSERT INTO public_partitions.table_'
|| date_part('year',NEW.eventdate)::VarChar
|| lpad(date_part('month',NEW.eventdate)::Varchar,2,'0')
|| lpad(date_part('day',NEW.eventdate)::Varchar,2,'0')
|| ' VALUES (NEW.*)');
RETURN NULL;
END;
$BODY$
LANGUAGE 'plpgsql'

This would obviously be very useful for partitioning - however if I
try this I get:

SQL state: 42601
Context: SQL statement "INSERT INTO public_partitions.summary_20080101
VALUES (NEW.*)"
PL/pgSQL function "insert_trigger" line 2 at EXECUTE statement

Thanks,

David.
