CFFI fails to build in postgres container

[j-manu]

Description/Steps to Reproduce

1. Install the latest master via kobo-install
2. Install backend only. Server setup
3. Activate AWS S3 for backups (not sure if this is relevant but this is the setup)
4. On python3 run.py -cb logs -f postgresql container contains the following error repeatedly

Hello @j-manu, Thank you for reporting this. We will release fix a soon. Did you only activate S3 for backups or did you also choose WAL-e?

It's been so long. I don't remember exactly :(
