=>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.
The bad data is inserted in recent days and we upgraded to 9.1.3 right
after it was released.

I am wondering how this could happen. I think if there was invalid
UTF8
bytes in the content, it shouldn't have been able to inserted into the
tmp_article table as I sometimes see similar errors when inserting
records to tmp_article. Am I right?
You are right in theory. A lot depends on your PostgreSQL version,
because
the efforts to prevent invalid strings from entering the database have
led to changes over the versions. Older versions are more permissive.
To test the theory that the contents of the table are bad, you can
test if the same happens if you
SELECT convert_to(content, 'UTF8') FROM tmp_article;
