If there were anything to happen here, then I think that it would be
hard to define what the statistics of the parent partition should
reflect. For example, the autovacuum and autoanalyze run times are I
think tricky as you cannot really define the last time autovacuum has
been run on the parent as the last time it has been run only only one of
the partitions or a sub-set of them. This gets also messier if you come
across multiple partition layers.
