PostgreSQL is used both as n8n's own data store (for workflow history, credentials, and execution logs) and as a target for the workflows themselves, letting you query, transform, and write data as part of any automation.\n\nThis setup is ideal when your automations handle **sensitive business data** that cannot flow through a third-party cloud, or when you need SQL logic at the heart of your pipelines — joining tables, aggregating metrics, or syncing CRM data into a warehouse. n8n's visual workflow builder lowers the barrier for non-engineers: marketing or ops teams can build and modify automations without writing code, while developers retain full control through code nodes for complex transformations.\n\nBecause n8n runs as a **long-lived process**, it supports webhook triggers, scheduled crons, and event-driven flows. PostgreSQL's reliability and ACID guarantees mean your automation history and state are never lost, even across restarts.

same database is not a good idea. n8n creates and migrates its own tables on every upgrade, so keep them in a dedicated database and put the tables your workflows read and write in a second one on the same instance.

Make sure pruning is enabled (EXECUTIONS_DATA_PRUNE) and set a retention window with EXECUTIONS_DATA_MAX_AGE, and consider EXECUTIONS_DATA_SAVE_ON_SUCCESS=none for high-frequency workflows, so only failed runs keep their data for debugging. On Neon this matters doubly, because storage is part of what you pay for once you leave the free plan.",{"question":324,"answer":325},"Can I use this stack with n8n Cloud instead of self-hosting?","Partly. On n8n Cloud, n8n keeps its own data on n8n's infrastructure, so PostgreSQL only plays its second role here: the database your workflows read and write. That database then has to be reachable from the internet, which makes Neon or another managed Postgres with SSL and an IP allowlist the practical pick rather than a database on a private server.
