Aiven has launched a Developer tier for its PostgreSQL service, starting at $5 per month. This tier offers more storage and keeps services running even when inactive, along with Basic support, making it suitable for test and personal projects.

Aiven has released PostgreSQL 18, which features significant performance improvements and new functionalities like asynchronous I/O, enhanced JOIN and GROUP BY operations, and parallel GIN index creation. This version allows more flexibility in schema evolution and smarter indexing with skip scans. Users can try PostgreSQL 18 with a free trial at Aiven.

PostgreSQL 18 introduces temporal constraints that simplify managing time-related data, allowing developers to maintain referential integrity across temporal relationships with ease. By utilizing GiST indexes and the WITHOUT OVERLAPS constraint, developers can efficiently handle overlapping time periods in applications without complex coding.
