The same happened to me a while ago, it was not a delete but an update.
Tom Lane posted something about this problem, the error appeared (as far as I can remember) when in the
same command a tuple got modified more than once (because of a join in a one to many relationed
table, for example).
Yours doesn't seem to be the case, but perhaps a trigger is trying to do an update or something.
Anyway, I remember Tom was working on it, I don't know if there is a patch already, but I solved the
problem rewriting the update query in a way that the same tupple didn't get parsed twice.
Hope it helps.
