wal2json is an output plugin for logical decoding. It means that the plugin have access to tuples produced by INSERT and UPDATE. Also, UPDATE/DELETE old row versions can be accessed depending on the configured replica identity. Changes can be consumed using the streaming protocol (logical replication slots) or by a special SQL API.
Tests currently running for 11,12,13. I don't expect them to fail for such as simple port. I am adding this port mostly because it's a dependency for Self-Hosted Sentry (https://github.com/getsentry/onpremise)
