My guess is that template0 is in danger of Xid wraparound and autovacuum wants to process it, but it can't for some reason. My second guess is that you are still running a version below 8.1.6, or were for a nontrivial amount of time. Said versions contain a bug that can make a future vacuum on template0 error out every time. -- Alvaro Herrera http://www.amazon.com/gp/registry/5ZYLFMCVHXC "Es filósofo el que disfruta con los enigmas" (G.
