Aiven is proud to launch the newest version of PostgreSQL, version 18, alongside with the open source community as the first managed PostgreSQL provider to support the latest version. This year we had three Aiveners join in on contributing to this major release, a trend which we hope to only see increase. Congrats to Patrick Stählin, Ronan Dunklau, and Thomas Krennwallner for your contributions to the codebase.
