Comment 3 for bug 1803107

If I understand Tino's branch and the problem correctly we will now manually request linking with bcrypt, so I think generate_random_uuid() can stay in (not tested).

If required, we could replace it with rand(), though I wouldn't like it. generate_random_uuid() is a cryptographic function so it creates "good" random values while the result of rand() shouldn't be used for security purposes. But, well, it probably doesn't really matters in our case anyway.
