PostgreSQL extension eliminates external workflow orchestration

pg_durable runs fault-tolerant long-running workflows as native SQL functions with built-in retry, checkpointing, and recovery—removing the need for separate job queues, schedulers, and orchestrators.

Summary

Developers can eliminate infrastructure glue (cron jobs, message queues, external orchestrators) by pushing workflow state directly into PostgreSQL. Execution survives crashes and resumes from checkpoints automatically, reducing distributed system complexity.

Why it matters

Implementation verdict

Replaces Temporal, external job schedulers, and async task queues for Postgres-native workloads. Requires PostgreSQL, Rust-based background worker, and DSL learning (~> and |=> operators). Ready now for vector pipelines and scheduled maintenance; production use depends on your tolerance for early-stage extensions.

Sources

1.workflows are expressed directly in SQL, with the extension handling execution concerns such as retries, fan-out, and recovery
2.some app-tier workers, queue consumers, or scheduler glue can disappear entirely
3.If the database crashes, restarts, or a step fails, execution resumes from the last durable checkpoint
4.The extension persists function execution state in PostgreSQL tables, allowing workflows to survive crashes, restarts, and failovers
