Heroku has long been committed to making PostgreSQL one of the best relational databases in the world. We’re also committed to giving you the ability to try the latest release as soon as it’s available. Today, we’re pleased to announce the public beta of Postgres 9.5 on Heroku.

PostgreSQL 9.5 brings a bevy of super exciting new features with the most prominent being the new UPSERT functionality. UPSERT gives you the expected behavior of an insert, or, if there is a conflict, an update, and is performant without the risk of race conditions for your data.

Do you have any favorite features coming in Ruby 2.3?
