PostgreSQL case conversion functions is a little bit buggy.
(Especially for Latin-N and Unicode encodings.) I've prepared a patch
[1] to fix a similar problem for Latin5 encoding. It wasn't tested so
much but works for your problem too:
template1=# CREATE DATABASE "testLatin" ENCODING = 'LATIN9';
CREATE DATABASE
template1=# \c testLatin
You are now connected to database "testLatin".
testLatin=# CREATE TABLE test
testLatin-# ( nombre varchar(20));
CREATE TABLE
testLatin=# COPY test FROM stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.

testLatin=# select * from test where upper(nombre) like 'ÑA%';
nombre
---------------
ñañoso pícaro
(1 row)
[1] You can find related patch (and discussion) @
http://archives.postgresql.org/pgsql-patches/2005-11/msg00173.php
address. It fixes case conversion problems for ILIKE, upper() and
lower() functions.
