This breaks with Node.js 14

[denschub]

For some reason, the top-level async function randomly decides to break with Node.js 14, and the process is quitting at the first await (in this case: trying to connect to the database), with no indication about what's happening.

This works fine in the LTS version, and it sill works in 13. I don't see anything obvious in the changelog either, so that's fun.
