System requirements¶

The Operator is validated for deployment on Kubernetes, GKE and EKS clusters. The Operator is cloud native and storage agnostic, working with a wide variety of storage classes, hostPath, and NFS.

Supported versions¶

The Operator 2.8.1 is developed, tested and based on:

PostgreSQL 18.1-1, 17.7-1, 16.11-1, 15.15-1, 14.20-1, 13.23-1 as the database. Other versions may also work but have not been tested.
pgBouncer 1.25.0-1 for connection pooling
Patroni version 4.1.0 for high-availability
PMM Client 3.5.0
PostGIS:
- version 3.5.4 for PostgreSQL 18,
- version 3.3.8 for PostgreSQL 17, 16, 15, 14, and 13

PostgreSQL RPMs rebuilt to disable debug assertions

The Percona Server for PostgreSQL (PSP) and Percona Distribution for PostgreSQL (PPG) RPM packages for PostgreSQL versions 13 through 18 released as part of the Q4 quarterly release were built with debug assertions enabled (--enable-cassert).

If you installed or updated PostgreSQL RPMs within the last four months, you may suffer performance degradation for the following versions: 18.1, 17.6, 17.7, 16.10, 16.11, 15.14, 15.15, 14.19, 14.20, 13.22, 13.23.

These packages have been rebuilt, and all users running RPM-based installations of the affected releases are strongly advised to update to the latest available packages.

To verify, run pg_config --configure. If the output includes --enable-cassert, then your installation is affected.

We do not recommend using the affected PostgreSQL versions listed above in production. We are working on a fix to fully address this issue. Find more information in Percona Distribution for PostgreSQL 18.1.1 release notes.

Supported platforms¶

The following platforms were tested and are officially supported by the Operator 2.8.1:

Google Kubernetes Engine (GKE) 1.31 - 1.33
Amazon Elastic Kubernetes Service (EKS) 1.31 - 1.34
Azure Kubernetes Service (AKS) 1.32 - 1.34
OpenShift 4.16 - 4.20
Minikube 1.37.0 with Kubernetes v1.34.0

Other Kubernetes platforms may also work but have not been tested.

Huge pages¶

We strongly recommend enabling huge pages on worker nodes for better stability and performance.
