Announcing Aiven for PostgreSQL® 14.0

We have upgraded to the latest PostgreSQL version. And it's great! Read on to find out what changes for you and what you need to do.

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.
