I've managed to reproduce this: the triggering condition is that a single autovac iteration has to VACUUM one table and then ANALYZE (no vac) another table that has an expressional index with a plpgsql function. It looks like we missed a path of control where ActiveSnapshot has to be re-set-up, but I'm not clear where. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
