Amazon Relational Database Service (Amazon RDS) for PostgreSQL 16 Release Candidate 1 (RC1) is now available in the Amazon RDS Database Preview Environment, allowing you to evaluate the pre-release of PostgreSQL 16 on Amazon RDS for PostgreSQL. You can deploy PostgreSQL 16 RC1 in the Preview Environment and have the same benefits of a fully managed database, making it simpler to set up, operate, and monitor databases. PostgreSQL 16RC1 in the Preview Environment also includes support for logical decoding on read replicas, AWS libcrypto (AWS-LC), and over 80 PostgreSQL extensions such as pgvector, pg_tle, h3-pg, pg_cron, and rdkit.
The PostgreSQL community released PostgreSQL 16 RC1 on August 31, 2023 that enables logical replication from standbys and includes numerous performance improvements. PostgreSQL 16 also adds support for SQL/JSON constructors and identity functions, more query types that can use parallelism, introduction of using SIMD CPU acceleration, and the ‘pg_stat_io’ view that provides statistics on I/O usage.
The Amazon RDS Database Preview Environment supports the latest generation of instance classes that are retained for a maximum period of 60 days and are automatically deleted after the retention period. Amazon RDS database snapshots that are created in the Preview Environment can only be used to create or restore database instances within the Preview Environment. You can use the PostgreSQL dump and load functionality to import or export your databases from the Preview Environment.
Amazon RDS Database Preview Environment database instances are priced the same as production RDS instances created in the US East (Ohio) Region.
