Hi,
My Task is to update our SuSE8.2 Postgres7.4.1 Webserver with tsearch2 to
the Version SuSE9.3 with Postgres8.1.3 and tsearch2.
The Services are running but i have some Problems with the
tsearch2
Configuration.
-------------------------------------------------------------------------------------------------------------------------------
old System:
SUSE8.2
Postgresql-7.4.1
tsearch2 (guide: References
on
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/tsearch2-ref.html
)
In this guide we do the kap. Configuration and Parser
new System:
SuSE9.3
Postgresql-8.1.3
tsearch2 (2 guides: tsearch2
with
UTF-8)
-------------------------------------------------------------------------------------------------------------------------------
My Steps:
1. I've download the new tsearch2.8.2.tar.gz for UTF-8 and replace the
tsearch2 folder
2. install the tsearch2 with make && make install, without problems
3. locale= de_DE.UTF-8,
4. I've download the *.med *.aff *.stop files from sai.msu.su/
tsearch2_german_utf8.zip german ispell dictionary (UTF-8)
extract in /var/lib/ispell/
5. Compiling the German Snowball Stemmer: with stem.c and stem.h (make &&
make install) /dict_de/..
6. After i restored our database with psql -d codasdb -f dump.sql
and psql -d codasdb -f tsearch2.sql
and psql -d codasdb -f dict_de.sql
7. I set the dict_initoption='/var/lib/ispell/german.stop' where dict_name
='de'; ???
8. INSERT INTO pg_ts_cfg (ts_name, prs_name, locale) values
('default_german', 'default', 'de_DE.UTF-8');
INSERT INTO pg_ts_dict (select 'de_ispell',
dict_init,
'DictFile="/var/lib/ispell/german.med",'
'AffFile="/var/lib/ispell/german.aff",'
'StopFile="/var/lib/ispell/german.stop"',
dict_lexize
FROM pg_ts_dict
where dict_name ='ispell_template');
9. SELECT set_curdict('de_ispell'); <- doesn't work with de_ispell i set it
('de'); ???
select 'Our first string used today'::tsvector; <-- runs
Now the Problem is:
codasdb=# select to_tsvector('PostgreSQL ist weitgehend konform mit dem
SQL92/SQL99-Standard, d.h. alle in dem Standard geforderten Funktionen
stehen zur Verfuegung und verhalten sich so, wie vom Standard gefordert;
dies ist bei manchen kommerziellen sowie nichtkommerziellen SQL-Datenbanken
bisweilen nicht gegeben.');
ERROR: invalid UTF-8 byte sequence detected near byte 0xe4
I've testet with
two
guides:
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/tsearch2_german_utf8.html
http://www.tauceti.net/roller/page/cetixx/20060401 (german)
Can
anyone
help?
