Announcing Aiven for PostgreSQL^® 14.0

Aiven is happy to release PostgreSQL 14.0, announced on 30 September 2021. This new version contains several new features and improvements. Here are the main highlights:

• Stored procedures can now return data via OUT parameters.
• The SQL-standard SEARCH and CYCLE options for common table expressions have been implemented.
• Subscripting can now be applied to any data type for which it is a useful notation, not only arrays. In this release, the jsonb and hstore types have gained subscripting operators.
• Range types have been extended by adding multiranges, allowing representation of noncontiguous data ranges.
• Numerous performance improvements have been made for parallel queries, heavily-concurrent workloads, partitioned tables, logical replication, and vacuuming.
• B-tree index updates are managed more efficiently, reducing index bloat.
• VACUUM automatically becomes more aggressive, and skips inessential cleanup, if the database starts to approach a transaction ID wraparound condition.
• Extended statistics can now be collected on expressions, allowing better planning results for complex queries.
• libpq now has the ability to pipeline multiple queries, which can boost throughput over high-latency connections.

Further details on all new features are listed in the PostgreSQL web page.
