I created a database with locale it_IT@[EMAIL PROTECTED]
 and I'm facing a weird=20
problem with tsearch. Let me show it:

tmptest=3D# SELECT * from pg_ts_cfg;
      ts_name     | prs_name |    locale
-----------------+----------+--------------
  default_russian | default  | ru_RU.KOI8-R
  simple          | default  |
  default         | default  | it_IT@[EMAIL PROTECTED]
(3 righe)

tmptest=3D# SELECT to_tsvector ('ciao mamma');
ERROR:  could not find tsearch config by locale
tmptest=3D# UPDATE pg_ts_cfg set locale =3D 'it_IT@[EMAIL PROTECTED]
' where ts_name
=3D=
=20
'default';
UPDATE 1
tmptest=3D# SELECT to_tsvector ('ciao mamma');
     to_tsvector
--------------------
  'ciao':1 'mamma':2
(1 riga)

tmptest=3D# UPDATE pg_ts_cfg set locale =3D 'it_IT@[EMAIL PROTECTED]
' where ts_name
=3D=
=20
'default';
UPDATE 1
tmptest=3D# SELECT to_tsvector ('ciao mamma');
     to_tsvector
--------------------
  'ciao':1 'mamma':2
(1 riga)

tmptest=3D# \q

So at first tsearch does not work. If I change it to it_IT@[EMAIL PROTECTED]
 it works =

and if I switch back to it_IT@[EMAIL PROTECTED]
 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=3D"it_IT@[EMAIL PROTECTED]
" and=
=20
  LANGUAGE=3D"it_IT"

Thanks,

Ottavio

PS: Im running a back****t of postgresql 8.1 on debian sarge.

Non c'e' piu' forza nella normalita', c'e' solo monotonia.
