encoding problem

folks

i have problems with encodings
the scenario is:

database: CREATE DATABASE "testLatin"
WITH OWNER = owner1
ENCODING = 'LATIN9';
test table:

CREATE TABLE test
( nombre varchar(20))
WITH OIDS;
ALTER TABLE test OWNER TO marcelo;
data:
nombre
---------
"maricón"
"ñañoso pícaro"

test statement
select * from test where upper(nombre) like 'ÑA%'
not data found !!!

any ideas?
best regards

MDC

pd: Unicode encoding has same result.
