Postgres
An open-source relational database management system known for its stability, extensibility, and standard SQL compliance. It is widely used in production environments and includes a built-in cost-model-based query optimizer.

TheYgent's durable runtime is built on DBOS—an embedded Python library that records workflow state into the Postgres the control plane already has, with no need to deploy a new stateful service.
LangGraph 应用可通过 Docker 镜像部署，使用 FastAPI 暴露接口，在 Kubernetes 上配置多副本并连接外部 Postgres 共享状态。
In one Mastra configuration, storing messages as a Postgres jsonb column caused property key order to change on read, thereby changing the prompt bytes and breaking the cache.
A Postgres conference talk compiled by ClickHouse put forward the view that "Postgres is not slow, your storage is slow," arguing that many complaints about Postgres performance are rooted in the configuration and selection of the underlying storage layer.
Google's agents can connect to Slack, Microsoft 365, Jira, and Postgres.
After selecting Postgres Chat Memory in n8n, conversation history will be written into a table named n8n_chat_histories.
The entire system of this solution runs completely on Docker containers, with the n8n service and the Postgres database each running in separate containers.
pg_hba.conf controls client authentication rules (who has permission to authenticate), while listen_addresses in postgresql.conf controls whether external network requests are accepted; both must be modified simultaneously to enable external connections.
To allow an n8n container to connect to a Postgres database from outside, you need to set listen_addresses to '*' in postgresql.conf and add subnet authorization rules in pg_hba.conf.
Containers within the same Docker Compose network can access each other using the container name as the hostname, so when n8n connects to Postgres, the Host field can be filled in directly with the container name postgres.

50%UnverifiedSetting listen_addresses to global listening means anyone may potentially connect to the database, so permissions should be tightened in production environments.

50%Unverifiedn8n's built-in memory is short-term by default and will be cleared after a service restart; for persistent cross-session memory, an external database such as Postgres or Redis must be connected.
50%UnverifiedBuilding the AgenticOS system requires Docker Compose 2.24 or higher, using Postgres with pgvector, Redis, and Prefect, with images supporting amd64 and arm64 architectures.
50%UnverifiedThe author recommends using Supabase or Postgres via Neon for the backend during the MVP phase, but acknowledges that this approach is not enterprise-grade and has limited security.
50%UnverifiedThe self-hosted AI starter kit is an open-source repository that packages n8n, Ollama, Qdrant, and Postgres into a single compose file.
50%UnverifiedSimple Memory temporarily stores context in server memory, and data will be lost after a restart; production-grade solutions typically persist data to external databases such as PostgreSQL or Redis.
50%UnverifiedThe user's existing architecture is centered on Claude, connected to internal MCP servers such as a Postgres database, a ticketing system, and a document index.
50%UnverifiedHindsight relies on a Postgres database as its underlying storage, making its deployment more complex than lightweight memory solutions.
50%UnverifiedForge can switch to Postgres/pgvector and Redis for production-level deployment.
