Get started with the Operator

Release Highlights

This release provides the following features and improvements:

PostgreSQL 18 support

You can now deploy PostgreSQL 18 on Kubernetes with the Operator. This latest major version of PostgreSQL delivers major improvements in performance, usability, and security, empowering you to make large-scale, mission-critical deployments more reliable and efficient.

Key improvements of PostgreSQL 18 are:

  • Asynchronous I/O (AIO) boosts throughput and reduces latency for sequential scans, vacuums, and other heavy operations. This means faster queries and smoother performance under load.
  • Queries can now use multicolumn B-tree indexes more effectively. Users benefit from faster lookups without needing redundant indexes.
  • Upgrades made via pg_upgrade no longer discard optimizer statistics. This reduces downtime and ensures consistent query performance after migrations.
  • You can now enforce PRIMARY KEY, UNIQUE, and FOREIGN KEY constraints over ranges of time. This is especially valuable for applications managing time-series or historical data.
  • Generated columns are now computed at read time by default. This reduces storage overhead and makes schema design more flexible.
