I have tried to do this the cleanest way possible, and not it is
working. Thank you for your help!

I'm going to provide detailed steps below to help others with similar
problems.

Steps taken:

#1. Installed a new virtual machine with the latest 10.2 RELEASE amd64
#2. Installed all available system updates via freebsd-update
#3. Downloaded the latest ports tree with "portsnap fetch; portsnap
extract".
#4. Configured PostgreSQL 9.4.6 server port with the following options:

* ICU - Use ICU for unicode collation
* INTDATE - builds with 64-bit date/time type
* NLS - Use internationalized messages
* SSL - build with openssl support
* TZDATA
* XML

There are the defaults, except for ICU. I have used 9.4 instead of 9.5
because that is the default postgresql server in FreeBSD 10.2

#5. I have compiled and installed the server from the ports tree. This
was a fresh BSD install, so all of the port dependencies were also
installed from source.
#6. Added this to /etc/login.conf:

postgres:\
    :lang=hu_HU.UTF-8:\
    :setenv=LC_COLLATE=hu_HU.UTF-8:\
    :tc=default:

and ran "cap_mkdb /etc/login.conf"

#7 Database initialization this way:

su -l pgsql
 initdb  --encoding=UTF-8 --lc-collate=hu_HU.UTF-8
--lc-ctype=hu_HU.UTF-8 --locale=hu_HU.UTF-8 -D /usr/local/pgsql/data

(Note: list all available locales with "locale -a" command)

#8. Created a new user and database:


template1=# create user test with password 'test' createdb;
CREATE ROLE
template1=# create database test with owner=test template=template0
encoding='UTF-8' lc_collate='hu_HU.UTF-8' lc_ctype='hu_HU.UTF-8';
CREATE DATABASE

Finally, got it working:

create table a (name text );
insert into a values ('a');
insert into a values ('á');
insert into a values ('Á');
insert into a values ('b');
insert into a values ('e');
insert into a values ('é');
insert into a values ('É');
insert into a values ('o');
insert into a values ('ó');
insert into a values ('ö');
insert into a values ('U');
insert into a values ('Ü');
insert into a values ('Z');


select name from a order by upper(name) asc;

"a"
"á"
"Á"
"b"
"e"
"é"
"É"
"o"
"ó"
"ö"
"U"
"Ü"
"Z"

I'm not sure what was the problem. There many places where I could have
forgotten something.
