Here is the rebased version of the patchset. Also, I updated the
commit messages for v16-0001 and v16-002 to make them look more like
the rest of the PostgreSQL commit messages. They include the link to
this discussion now as well.

IMO v16-0001 and v16-0002 are in pretty good shape and are as much as
we are going to deliver in PG15. I'm going to change the status of the
CF entry to "Ready for Committer" somewhere this week unless someone
believes v16-0001 and/or v16-0002 shouldn't be merged.
