PostgreSQL 16

PostgreSQL 16 optimizes query parallelism, introduces bidirectional logical replication, and enhances monitoring via the pg_stat_io view.

Version 16 sharpens the world's most advanced open source database with significant performance gains in bulk loading and query execution. It introduces ICU collation support as the default for better internationalization and adds the pg_stat_io view for granular I/O observability. Developers benefit from expanded SQL/JSON syntax (including IS JSON predicates) and the ability to run logical replication from standby servers, reducing the load on primary nodes. This release solidifies Postgres as the standard for ACID-compliant workloads requiring high-throughput parallelism and robust security.
