Postgres

Lakebase is a database service launched by Databricks for AI application scenarios, representing transactional database capabilities built on top of the Lakehouse architecture.

Storage-compute separation architecture achieves second-level elastic scaling of compute resources by decoupling the storage layer from the compute layer, allowing storage to scale independently without data migration.

Supabase's real-time subscription feature is based on PostgreSQL's logical replication protocol and pushes database changes to clients in real time via WebSocket.

EVE supports plugging in open-source adapters such as Postgres, OpenAI Responses API, and Docker, and can also be deployed to Vercel in one click using Vercel Workflows, Sandbox, and Vercel Connect.

The current version of the database Agent supports only SQL databases, with Postgres and Cosmos being rapidly onboarded.

Supabase is built on standard Postgres, and data and application logic can be migrated to other hosting solutions.

Row Level Security is a native Postgres feature that allows policies to be defined on tables to automatically filter visible or writable rows based on the current user's identity.

Every Postgres update must go through the WAL flush to disk and acquire a row lock, and the old row is not deleted immediately but left for the vacuum process to clean up.

A single Postgres instance can handle roughly 10,000 to 50,000 writes per second.

OntoGr runs on top of FalkorDB or Neo4j, and can optionally use pgvector or Postgres; a background consolidation task handles deduplication, summarization, scoring, and archiving; the LLM and embedder are bring-your-own.

According to MarkTechPost, durable-harness is designed to cover three runtime environments: the Vercel platform, Postgres, and local laptops.

On Serverless, relying on in-memory storage for session state is unreliable; session state needs to be externalized to persistent storage (such as Postgres), reading the latest state from storage on each call and writing it back after execution.

Common Checkpointer implementations include InMemorySaver (valid only within the process, suitable for testing) and persistence implementations based on SQLite/Postgres/Redis (suitable for production).

durable-harness writes to the World interface, so the same agent can migrate from one World to another without code changes: use Vercel World on Vercel, local files during development, and Postgres, MongoDB, Redis, or Turso when self-hosting.

In durable-harness, migrating an agent to Postgres only requires setting two environment variables, WORKFLOW_TARGET_WORLD and WORKFLOW_POSTGRES_URL.

According to Databricks' official introduction, Lakebase Postgres is a service that combines a Postgres-compatible database with data lake capabilities.

Statewave uses the Apache-2.0 license, depends on Postgres 14+, pgvector, and Python 3.11+, and provides HMAC-SHA256-signed receipts and a replay endpoint that can reconstruct the four properties of an audit trail.

Hindsight uses the MIT license, runs on Postgres or embedded pg0, separates facts and experiences from consolidated observations and mental models, the reflect step synthesizes across layers, and four recall paths run in parallel; it can reconstruct observations traced back to experiences, but requires more model calls.

Statewave has no managed cloud, so you must operate Postgres yourself; it has no entity relationship graph; no multimodal RAG; tenant isolation is at the application layer rather than Postgres row-level security; and server-side CI testing has been done only on Linux.
