There is no attachment in this thread, so it's not showing up in the
commitfest entry (which will need to be moved to next open
commitfest), so it's not getting CI testing:

https://commitfest.postgresql.org/patch/5726/

Note that the whole series must be attached in a single email, or it
won't get automated testing.
