This is highly annoying, but thanks for raising the issue.

I feel inclined to solve this by adding a release note saying that if you are one of the tiny number of people who used v2020-09-11 to send or receive transactions with metadata, then you should delete your wallet database and restore from genesis.

@rvl it should be possible to fallback on the old parsing method when de-serializing from the database, at least temporarily. Then, it'll be replace with the right format when re-inserted.
