The places in the intarray code that you tried to "fix" in your patch at the start of this thread are not dealing with data that came from a tuple, but from data that came from a decompress method. It's expected that the decompress method does the detoasting. So I think you've mis-analyzed the problem. That's especially true since you are claiming that the existing code is already buggy when in fact no such bugs have been reported (and clearly intarray has been running with toasted array values for years). -- Andrew, Supernews http://www.supernews.com - individual and corporate NNTP services ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
