Hello

it works for me

postgres=# create schema export;
CREATE SCHEMA
Time: 45,918 ms
postgres=# create table public.a(a varchar);
CREATE TABLE
Time: 91,385 ms
postgres=# create table export.a(a varchar);
\CREATE TABLE
Time: 9,462 ms
postgres=# create function ftrg() returns trigger as $$begin insert
into export.a values(new.*); return new; end$$ language plpgsql;
CREATE FUNCTION
Time: 486,395 ms
postgres=# \h CREATE trigger
Command:     CREATE TRIGGER
Description: define a new trigger
Syntax:
CREATE TRIGGER name { BEFORE | AFTER } { event [ OR ... ] }   ON table [ FOR [ EACH ] { ROW | STATEMENT } ]   EXECUTE
PROCEDUREfuncname ( arguments )
 

postgres=# CREATE TRIGGER aaa after insert on public.a for each row
execute procedure ftrg();
CREATE TRIGGER
Time: 5,848 ms
postgres=# insert into public.a values('ahoj');
INSERT 0 1
Time: 5,179 ms
postgres=# SELECT * from export.a ; a
------ahoj
(1 row)

postgresql 8.3

You will need to show the actual query, but I suspect you have an extra period 
in your table name. Instead of public.table_name you have something like 
public.table.name.

Thanks Adrian,

I casted a column to a type with "value::<schema>.<table>.<column>%type"
That was the problem.
