   > Nice find, I think you fixed a long standing bug. @alamb do we need to backport this to any previous releases, given that they were producing incorrect results?
   
   What I think we should do is file a ticket with some example queries where this bug results in incorrect results. Such queries I think will help us to understand the impact, and depending on that we can figure out if we want to backport this change
