CitusDB 3.0 is based on PostgreSQL 9.3.2 and is binary incompatible with CitusDB 2.0
We are excited to announce the general availability of CitusDB v3.0. Apart from various bug fixes and performance improvements, the major features in this release include:
CitusDB 3.0 is based on PostgreSQL 9.3.2, and is binary incompatible with CitusDB 2.0. As a result, the install path for the new version has changed from /opt/citusdb/2.0 to /opt/citusdb/3.0 in order to allow for multiple versions of Citus DB to be installed in parallel.
If you are running CitusDB 2.0 and want to upgrade to v3.0, you will need to run pg_upgrade on your all nodes, and manually reload your distributed metadata. For specifics, please get in touch with us so we can assist with the upgrade process. If you are downloading and using CitusDB for the first time, please follow the installation instructions found in the CitusDB documentation page.
