My db is in utf-8, I have a row in my table say tmp_article and I wanted to generate ts_vector from the article content:
select to_tsvector(content) from tmp_article;
But I got this error:
ERROR: invalid byte sequence for encoding "UTF8": 0xf481

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?

This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".

Try to set client_encoding='LATIN1'

and then execute
