Update of /cvsroot/monetdb/sql/src/common In directory 23jxhf1.ch3.sourceforge.com:/tmp/cvs-serv3519/common
Modified Files: Tag: Feb2009 sql_types.mx Log Message: reverting addition of prob() aggregation, as it would break db compatibility
Thanks! (In particular for properly doing it using CVS commands, only!)
I prevented propagation of this "undo" to the developlment trunk; the "do" had already been propagated yesterday; hence, the prod() aggregation is now avilable in the development trunk.
I would dearly like to see that db backward compatibility is also maintained between stable and devel. In other words, there has to be a smooth way forward without having to resort to dump/restore. So I'm also not terribly happy with the change as it is now in the devel branch.
... right; good point --- maybe I was a bit to "generous", here, easily accepting this change as-is for the development branch ... indeed, we should aim for maitaining db backward compatibility also between stable and devel.
