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?
