Do you use any nonstandard text search parsers or dictionaries?
What is the text search configuration you use (parameter
default_text_search_config)?
Yes, I'm using a Chinese tsearch2 plugin called nlpbamboo and the
default default_text_search_config is 'chinesecfg'. I tested select
to_tsvector('english',content) from tmp_article and this works. So it's
the problem of nlpbamboo?
That's probably the problem - it seems to emit something that is
not proper UTF-8 sometimes.
Do you get the error if you try Chinese settings without nlpbamboo?
btw, what's the meaning of Please don't top post.? I
don't understand but sorry if I caused any problem.

=SELECT convert_to(content, 'UTF8') FROM tmp_article; This works. My pg is at latest 9.1.3 on ubuntu 10.04 server. We have millions of data in the db but this is the only one we met the problem.
