This is a reproduction scenario for the problem described in the comments on https://stackoverflow.com/a/34401374/53538 - how UPDATE causes all UUIDs to be the same.

To run, put all 3 files in the same directory and run make. Built and tested on Ubuntu 20.04.

Asciinema of me running this is at https://asciinema.org/a/wiUgn77W0PkbWHfgJktBph0WW
