Citus 13.0 Released!

PostgreSQL 17 supported on Citus

Citus 13.0 adds support for Postgres 17. There are many new features that are enabled by PG17 that are particularly interesting for Citus users:

• JSON_TABLE() support in distributed queries
• Propagate "MERGE ... WHEN NOT MATCHED BY SOURCE" syntax
• Expanded functionality on distributed partitioned tables
• Propagate new EXPLAIN options: MEMORY and SERIALIZE
• Optimizer improvements

In addition to support of Postgres 17 Citus 13.0 also includes:

• Bug fixes that address some crashes caused by unsafe catalog access, and segmentation faults in distributed procedures
• Fixes to resolve issues related to role synchronization across nodes, server crashes in specific cluster configurations, and improve handling of shard placement when new nodes are introduced without required reference data
