I'd have expected that to grind for a really long time, gradually filling your disk, until you got an out-of-disk-space kind of error; if you didn't notice and stop it first. There aren't (supposed to be) any long-term memory leaks in query processing, other than than the known issue of pending trigger events, which you say you haven't got on this table. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
