I believe this is what the SQL92 standard asks for. It seems to want
<column name> = <update source> rather than something like
<column reference> = <update source>

My memory is rather flaky but I vaguely remember a recent discussion on
something similar (maybe column names in insert lists?) that made it sound
like it might be possible to convince a change, but it would probably have
to properly error on cases where the names didn't match properly.
