What is Postgres Operator?

Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.

Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.

What is Rivet?

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

Postgres Operator vs Rivet: editorial side-by-side

P0.0

Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.

◆ Current state

Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.

◆ Where it's heading

The v2 line is still in stabilization, with each patch carrying a breaking change of some kind. The AWS and IRSA fixes suggest EKS users are the main early adopters.

◆ Prediction

Expect further 2.0.x patches on a roughly six-week cycle; a 2.1 feature release is not visible in the entries.

7.5

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

◆ Current state

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

◆ Where it's heading

Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.

◆ Prediction

Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
