Earlier this month, PostgreSQL 10.0 was released. Today, we are excited to announce PostgreSQL 10 is available in beta on Heroku, bringing a number of notable feature and performance improvements to our managed PostgreSQL database service.
The beta provides customers who want to try out the new release an easy way to do so, while customers who are happy with the current version can continue to stay on version 9.6 until we make version 10 generally available. Also, new databases will continue to default to version 9.6 until we release version 10 to GA.
