I feel uneasy about using binary data in sql queries, without special blob handling, but I guess it should work until we're proven otherwise.

Looks good. I suppose you tried something like this: https://git.kolab.org/rKa3448e46572c9bcba39702689d31e77bfeaa1d26, but it didn't give access to the email/walletId?

This diff consists of multiple commits that I've used for the migration. Since we're already using it like this I'd like to mostly just get it merged, but I'm open to small adjustments (the rest we can improve later on IMO).

Cleanup

I think for some of these jobs we should probably keep trying at an hourly or even daily interval. So if we e.g. have infrastructure issues over a couple of hours the system still eventually recovers without manual intervention.
