OK. That's a bit older than I'd like --- if you read the release notes you will notice there are a bunch of corner-case-data-corruption fixes since then. However, I do not think that any of the known issues would manifest in the way you're describing, so whatever you're seeing is probably still a live bug. Please see if you can make a test case. regards, tom lane
