Hmm ... is it possible to create a test that verifies this? I suppose
we could have a non-utf8 value as bytea.
I have not any idea. The problem is in utf8 encoded xml with bad header. There is dependency to database encoding and supported locales.
Maybe I can simulate it with cast without function from bytea to xml - but it looks more than little bit dirty
