Thanks for the suggestion, regrettably I've already made those changes. After examining the call sites, I identified 35 that might need changing. Of those, about 30 were changed to use systable_beginscan, while a few others use declared snapshots instead. So not a great effort and worth doing the by-hand inspection. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
