Amazon Aurora PostgreSQL 18.1 Available in RDS Preview
🚀 Amazon Aurora PostgreSQL-Compatible Edition now supports PostgreSQL 18.1 in the Amazon RDS Database Preview Environment, enabling evaluation of the new engine on Aurora without self-installation or manual provisioning. PostgreSQL 18.1, released September 9, 2025, adds skip scan for multicolumn B-tree indexes, improved WHERE handling for OR/IN, parallel GIN index builds, and join enhancements. Observability gains include buffer usage counts, index lookup details, and a per-connection I/O utilization metric. Preview clusters are retained up to 60 days and are priced the same as production Aurora instances in the US East (Ohio) Region.
