Overview

Enables n8n workflows to publish and listen on PostgreSQL event channels, facilitating real‑time inter‑workflow communication and result exchange for automation builders.

Nodes & Operations

PostgreSQL Send To Channel

Sends a command to a PostgreSQL event channel and waits up to a specified timeout for a remote workflow to process it, returning the event state and result data. It blocks the workflow until processing completes and provides the outcome to the calling node.

  • Default · Default — Send a command to a PostgreSQL-backed event channel, wait up to a specified timeout for a remote workflow to process it, and return the event state and result data.

PostgreSQL Event Trigger

Listens for entries in a PostgreSQL event channel and triggers the workflow when new events arrive, polling the database at a configured interval. When an entry is detected, it emits a workflow trigger containing the event payload.

  • Default · Default — Listen for and emit workflow triggers based on event entries in a specified PostgreSQL event channel, polling the database at a configured interval.

PostgreSQL Write Result

Updates a PostgreSQL event channel record with the execution result and success flag based on the provided Event ID, storing the outcome of a completed workflow.

  • Default · Default — Update a PostgreSQL event channel record's state and store the workflow execution result based on the provided Event ID and success flag.
