Postgres as Execution Engine: The Queue and Workflow Land Grab

Microsoft open-sourced pg_durable, a Postgres extension for durable execution, and the HN thread immediately compared it to DBOS, pgQueue, and Temporal. The comment that got the most traction: '2026 is the year of the Postgres queue.' Multiple projects are now racing to make Postgres the substrate for workflow orchestration, a job that used to belong entirely to dedicated systems like Airflow or Temporal.

The pattern is Postgres absorbing adjacent infrastructure categories. Queues, durable execution, vector search, time-series: every year Postgres eats another specialty database's lunch. pg_durable is Microsoft's entry into this, and the fact that they open-sourced it suggests they want ecosystem adoption, not a proprietary moat.

The pushback in the thread was real: several engineers argued this is the wrong abstraction, that storing control flow in a database couples your application logic to your persistence layer in ways that create long-term pain. The comparison to Temporal was sharp: pg_durable explicitly says it is not for workflows that span many heterogeneous systems, which is exactly what most serious workflow orchestration does.
