What is Postgres Operator?

Zalando's Postgres Operator finally shipped v2 — and had to reissue it within a day.

The Postgres Operator has crossed from a long-running 1.x line into a v2 major release requiring an explicit migration. v2 brings Postgres 18 support, NodePort services, TopologySpreadConstraints, an ARM-compatible pooler image, IRSA for EKS, and globally configurable maintenance windows. The initial v2.0.0 tag shipped with an OperatorConfiguration CRD type mismatch that broke GitOps pipelines and was superseded by v2.0.1 the same day.

What is pgBackRest?

PostgreSQL 19 support lands, and pgBackRest stops letting you run most commands as root.

2.59.0 in July added PostgreSQL 19 support and changed a long-standing default: only the restore command may run as root now, with anything else requiring an explicit allow-root. The same release ships a pregenerated distribution tarball so packagers no longer need the code-generation toolchain, and picks up an optional libsystemd dependency. Before it, 2.58.0 concentrated on object storage — HTTP support for S3, GCS and Azure, Azure managed identities, experimental S3 EKS pod identity, and configurable TLS cipher suites.

Postgres Operator vs pgBackRest: editorial side-by-side

P6.3

Zalando's Postgres Operator finally shipped v2 — and had to reissue it within a day.

◆ Current state

The Postgres Operator has crossed from a long-running 1.x line into a v2 major release requiring an explicit migration. v2 brings Postgres 18 support, NodePort services, TopologySpreadConstraints, an ARM-compatible pooler image, IRSA for EKS, and globally configurable maintenance windows. The initial v2.0.0 tag shipped with an OperatorConfiguration CRD type mismatch that broke GitOps pipelines and was superseded by v2.0.1 the same day.

◆ Where it's heading

The 1.x releases — shipped under animal codenames rather than versions — were incrementally widening operator control over child resources: owner references, per-cluster maintenance windows, inherited annotations, PDBs for bootstrap protection. v2 consolidates that into a breaking release and picks up the platform work the 1.x line kept deferring: ARM images, EKS-native identity, spread constraints. The recurring pattern of releases shipping incomplete — missing UI and logical-backup images in one, a pipeline-breaking CRD in another — suggests release engineering is the weak point rather than the code itself.

◆ Prediction

Expect a 2.0.x patch stream shaking out migration problems from the v2 CRD changes before any new features land. Postgres 18 support arriving here also implies Spilo image updates will keep pacing upstream Postgres releases.

P2.5

PostgreSQL 19 support lands, and pgBackRest stops letting you run most commands as root.

◆ Current state

2.59.0 in July added PostgreSQL 19 support and changed a long-standing default: only the restore command may run as root now, with anything else requiring an explicit allow-root. The same release ships a pregenerated distribution tarball so packagers no longer need the code-generation toolchain, and picks up an optional libsystemd dependency. Before it, 2.58.0 concentrated on object storage — HTTP support for S3, GCS and Azure, Azure managed identities, experimental S3 EKS pod identity, and configurable TLS cipher suites.

◆ Where it's heading

Two currents run through this window. The first is keeping pace with PostgreSQL itself, where support arrives experimentally a release early — PostgreSQL 18 in 2.55.0, 19 in 2.59.0 — so the backup tool is ready before the database is. The second is a steady move toward cloud-native identity and away from ambient privilege: managed identities and pod identity replace stored keys, and the root restriction narrows what a compromised invocation can reach.

◆ Prediction

Given the pattern of adding experimental support one PostgreSQL cycle ahead and hardening defaults as the release lands, the next release is likely to promote PostgreSQL 19 support out of its initial state. The notes do not say whether allow-root will be deprecated further.
