Thanks for the quick rework. I like this design much better and I think
this is pretty close to committable. Here's a rebased copy with some
small cleanups (most notably, avoid calling pgstat_propagate_changes
when the partition doesn't have a tabstat entry; also, free the lists
that are allocated in a couple of places).
I didn't actually verify that it works.
