As I mentioned before, your code works on special cases (insert with all the columns) and those are very few cases.
Try this
CREATE TABLE foo (a int, b int);
CREATE TABLE job_2011_11 (c int, d int);
CREATE OR REPLACE FUNCTION job_insert_trigger()
RETURNS TRIGGER AS
$BODY$
DECLARE
currentTableName character varying := 'job_' || '2011_11';
BEGIN
EXECUTE 'INSERT INTO '|| currentTableName || ' values ' || (NEW.*);
RETURN NULL;
END;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
CREATE TRIGGER job_insert_trg BEFORE INSERT ON foo
FOR EACH ROW EXECUTE PROCEDURE job_insert_trigger();
INSERT INTO foo (a, b) VALUES (1, 2);
INSERT INTO foo (a) VALUES (10);
ERROR:
LINE 1: INSERT INTO job_2011_11 values (10,)
^
QUERY: INSERT INTO job_2011_11 values (10,)
CONTEXT: PL/pgSQL function "job_insert_trigger" line 5 at instruction EXECUTE
Regarding the self contained test for EXECUTE it's the same code.
In the trigger the use of this code doesn't work :
EXECUTE 'INSERT INTO job_2011_11 values (NEW.*)';
but
this one does work
INSERT INTO job_2011_11 values (NEW.*);
So it looks like a trouble with EXECUTE to me!

self-contained test case. For example, this similar example works
fine:
CREATE TABLE foo (a int, b int);
CREATE TABLE job_2011_11 (c int, d int);
CREATE OR REPLACE FUNCTION job_insert_trigger()
RETURNS TRIGGER AS
$BODY$
DECLARE
currentTableName character varying := 'job_' || '2011_11';
BEGIN
EXECUTE 'INSERT INTO '|| currentTableName || ' values ' || (NEW.*);
RETURN NULL;
END;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
CREATE TRIGGER job_insert_trg BEFORE INSERT ON foo
FOR EACH ROW EXECUTE PROCEDURE job_insert_trigger();
INSERT INTO foo (a, b) VALUES (1, 2);
