What it does
Isolation the database enforces. Context that survives every thread, job and message. A test that proves it, not a README that claims it. 0.4.0 · Apache 2.0 · on Maven Central · Java 17+ · Spring Boot 3.3+ Your connection pool reuses sessions. Set the tenant on one, miss the reset, and the next request inherits it — reading another customer’s data with no error, no exception, and nothing in your logs. Your tests will not catch this. Tests don’t contend for pooled connections. It is one of about six mistakes every hand-rolled multi-tenancy implementation makes, and they are all silent. TenantLayer is those six mistakes, already made and already fixed. Because you will forget once, in four…from tenantlayer.io

Supabase-Test – Fast Isolated Postgres DBs for Testing Supabase RLSNov 2025 · npmjs.com · ▲30Hi HN — we've built a testing framework for Supabase that spins up fast, isolated Postgres databases for each test case. It’s designed to make RLS policies easy to validate with real database state, without global test fixtures or mock auth. Features: - Instant isolated Postgres DBs per test - Automatic rollback after each test - RLS-native testing with `.setContext()` for auth simulation - Flexible seeding (SQL, CSV, JSON, JS) - Works with Jest, Mocha, and any async test runner - CI-friendly (runs cleanly in GitHub Actions) We also published example projects and a free set of tutorials:…
Light implementation of Event Sourcing using PostgreSQL as event store2023 · github.com · ▲231Hi everyone, If you have a Java Spring Boot application with a PostgreSQL database, you can implement Event Sourcing without introducing new specialized databases or frameworks. If you have an application dealing with an entity called Order, you should adopt Event Sourcing to keep track of all changes, and know how the Order got into the current state. Event Sourcing gives you: 1. the true history of the system (audit and traceability), 2. the ability to put the system in any prior state (debugging), 3. the ability to create read projections from events as needed to respond to new demands.…
Serverless Postgres2024 · github.com · ▲159This is a MVP for Serverless Postgres. 1/ It uses Fly.io[0], which can automatically pause your database after all connections are released (and start it again when new connections join). 2/ It uses Oriole[1], a Postgres extension with experimental support for S3 / Decoupled Storage[2]. 3/ It uses Tigris[3], Globally Distributed S3-Compatible Object Storage. Oriole will automatically backup the data to Tigris using background workers. I wouldn't recommend using this in production, but I think it's in a good spot to provoke some discussion and ideas. You can get it running…

Cloud-Ready Postgres MCP Server2025 · github.com · ▲167Hey HN, I built pg-mcp, a Model Context Protocol (MCP) server for PostgreSQL that provides structured schema inspection and query execution for LLMs and agents. It's multi-tenant and runs over HTTP/SSE (not stdio) Features - Supports multiple database connections from multiple agents - Schema Introspection: Returns table structures, types, indexes and constraints; enriched with descriptions from pg_catalog. (for well documented databases) - Read-Only Queries: Controlled execution of queries via MCP. - EXPLAIN Tool: Helps smart agents optimize queries before execution. - Extension…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
