Milena, do you consider this a bug fix or a new feature? if the former, it will not be in the upcoming release, since it has not (yet) been checked in to the Feb2009 release branch... in case you consider an exceptional back-port of this checkin to the Feb2009 release branch, please make sure you od this using the approriate CVS commands to ensure that the identical changes are applied --- see, e.g., page 14 of http://homepages.cwi.nl/~manegold/Presentations/MonetDBdevTTT.pdf for details --- don't hesitate to ask inc ase you need help ...
