Postgres transactions are a distributed systems superpower

Co-locating workflow state and application data within the same Postgres database enables distributed systems to leverage ACID transactions to eliminate complex idempotency and atomicity challenges that typically require separate bookkeeping infrastructure. This architectural approach simplifies workflow management by ensuring database updates and workflow checkpoints commit together atomically, reducing operational overhead and the risk of data inconsistencies caused by partial failures. For IT organizations, this means reduced complexity in distributed system design, fewer specialized tools required, and stronger data consistency guarantees without the operational burden of managing separate workflow engines and outbox systems.
