On the topic of n_distinct.
I am not sure whether I am misinterpreting something, or if it is a bug (probably former) however, when using partitions, are not n_distinct_inherited supposed to propagate to the child partitions? It does not seem to do so. (Yes, I run Analyze after setting the variable) I had to set the n_distinct separately on all partitions to get the desired planer behavior, but I thought that setting n_distinct_inherited was supposed to prevent manually setting the partitions.
