[to_tsvector] German Compound Words

Hi everybody,

what do I need to do in order to enable compound word handling in
PostgreSQL tsvector implementation?

I run an Ubuntu 14.04 machine, PostgreSQL 9.3, have installed package
hunspell-de-de and already created a new dictionary as described here:
http://www.postgresql.org/docs/9.3/static/textsearch-dictionaries.html#TEXTSEARCH-ISPELL-DICTIONARY

CREATE TEXT SEARCH DICTIONARY german_hunspell (
TEMPLATE = ispell,
DictFile = de_de,
AffFile = de_de,
StopWords = german
);

Furthermore, created a new test text search configuration (copied from german) and updated all parser parts where the german_stem dictionary is used so that it uses german_hunspell first and then german_stem.

However, ts_vector still does not work for the compound words such as:

wasserkraft -> wasserkraft, kraft
schifffahrt -> schifffahrt, fahrt
blindflansch -> blindflansch, flansch

etc.

What have I done wrong here?
