Partitioning versus autovacuum

However as far as I can tell autovacuum will never actually trigger this analyze. Because we never generate any update records for the parent table in the statistics. Have I missed something?

I didn't find any discussion of this in the threads from when partitioning was committed but there were a lot of discussions and I could easily have missed it.

Is there a story for this? Some way to configure things so that autovacuum will analyze partitioned tables?

Or should we look at doing something? Maybe whether we analyze a child we should also update the parent -- and if there's no stats yet run analyze on it?

This may be a serious enough problem for users that it may warrant backpatching. Not having any stats is resulting in some pretty weird plans for us.
