The following bug has been logged online:

Bug reference: 4253
Logged by: Giorgio Valoti
Email address: giorgio_v(at)mac(dot)com
PostgreSQL version: 8.3.3
Operating system: Mac OS X 10.5.3
Description: to_tsvector: error with some configurations
Details:

Using every language containing the "a grave" letter (c3 a0) causes an error
when the function "ts_vector" is invoked.

test=> select to_tsvector('italian','prova');
ERROR: invalid byte sequence for encoding "UTF8": 0xc3
HINT: This error can also happen if the byte sequence does not match the
encoding expected by the server, which is controlled by "client_encoding".

test=> select to_tsvector('french','prova');
ERROR: invalid byte sequence for encoding "UTF8": 0xc3
HINT: This error can also happen if the byte sequence does not match the
encoding expected by the server, which is controlled by "client_encoding".

test=> select to_tsvector('portuguese','prova');
ERROR: invalid byte sequence for encoding "UTF8": 0xc3
HINT: This error can also happen if the byte sequence does not match the
encoding expected by the server, which is controlled by "client_encoding".

Hmm, works for me:

z=# select to_tsvector('italian','prova');
to_tsvector
-------------
'prov':1
(1 row)

What database encoding (server_encoding) are you using? Is it possible
that the text search configuration files have been rewritten into a
non-UTF8 encoding?
