Active Active in Postgres 16

> The expectation after committing is that last_name will be equal to Jones and email will be bugs.bunny@acme.com. Commit the transaction in pg1 and then in pg2. What happens?

> Now both rows are out of sync. In pg1, the update of the email was lost and in pg2 the update of last_name was lost. This happens because the entire row is sent over during logical replication and not just the fields that were updated. In such cases, even eventual consistency is not possible.

Hmm, this makes it seem rather useless. Or at least not useful for what I would expect: keeping two Postgres instances in sync.
