If you think a cut version of Tomas' patch is appropriate, then the usual response is to give a review that says "Tomas, I think a cut down version is appropriate here, can we reduce the scope of this patch for now?". If you have done that and he refuses to listen, then a separate patch version is appropriate. Otherwise we should just reject this second patchset to avoid confusion and to avoid encouraging people to take this approach. -- Simon Riggs http://www.2ndQuadrant.com/ <http://www.2ndquadrant.com/> PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
