Aurora keeps coming along in leaps and bounds, congratulations to the team, this is a fantastic achievement!
I only wish that every new feature didn't inevitably come with the caveat that it's only for the MySQL flavour of Aurora.
I understand both the engineering and product development reasons for doing so (different stack and MySQL is undoubtedly a much larger customer base), but it always makes these announcements a little underwhelming as an Aurora Postgres user.
