hmm, but you've added a case for SpecialJoinInfo, is there a good reason not just to do the translation by just adding an EquivalenceClass case to adjust_appendrel_attrs_mutator() then just get rid of the new "replace" flag in add_child_rel_equivalences()? That way you'd also remove the churn in the couple of places you've had to modify the existing calls to add_child_rel_equivalences(). -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
