Ah, I see. In that case I think to_date would have disappointed you
even if IYYY-IW-DY did work, since the inputs do not appear to be
checked against the localised versions of the day names. They are
only checked against the hard-coded English names. to_date and
to_char are asymmetric in this sense -- localisation only happens on
the way out.
