Thanks Oliver! Is there a way to handle it in hql? E.g if( exists(is_pageview),is_pageview,null)? Finding out if field exists by observing query crash seems wrong ))

That's not a bug. The complexity of regenerating ~60 days of data,
where a day is 24*60*125000 rows, is extreme, and adding new fields
means doing just that - regenerating the entire thing. As such, the
decision was made to add to the field definition and only add actual
values going forward from the point at which the patch was merged.
This was true of the is_pageview calculation, the user agent data and
the geolocation elements previously added, and is still true now.
