problem with tsearch and utf-8 on postgresql 8.1

[Ottavio Campana <ottavio@xxxxxxxxxxxxx>]

I created a database with locale it_IT@UTF-8, and I'm facing a weird 
problem with tsearch. Let me show it:

tmptest=# SELECT * from pg_ts_cfg;
     ts_name     | prs_name |    locale
-----------------+----------+--------------
 default_russian | default  | ru_RU.KOI8-R
 simple          | default  |
 default         | default  | it_IT@UTF-8
(3 righe)

tmptest=# SELECT to_tsvector ('ciao mamma');
ERROR:  could not find tsearch config by locale
tmptest=# UPDATE pg_ts_cfg set locale = 'it_IT@euro' where ts_name = 
'default';
UPDATE 1
tmptest=# SELECT to_tsvector ('ciao mamma');
    to_tsvector
--------------------
 'ciao':1 'mamma':2
(1 riga)

tmptest=# UPDATE pg_ts_cfg set locale = 'it_IT@UTF-8' where ts_name = 
'default';
UPDATE 1
tmptest=# SELECT to_tsvector ('ciao mamma');
    to_tsvector
--------------------
 'ciao':1 'mamma':2
(1 riga)

tmptest=# \q

So at first tsearch does not work. If I change it to it_IT@euro it works 
and if I switch back to it_IT@UTF-8 it then works even with that locale.
I cannot understand the reason why it happens. By disconnecting from the 
db and connecting again the problem is still there. Do you have any idea 
why it happens?

I don't know if it matters, on the systems I have LANG="it_IT@euro" and 
 LANGUAGE="it_IT"

Thanks,

Ottavio

PS: Im running a backport of postgresql 8.1 on debian sarge.
