MysticMind.PostgresEmbedA real PostgreSQL server in your .NET tests

Start any Postgres version from code, extensions included, on Windows, Linux and macOS. No Docker, no local install.

Any version

An exact version such as 17.6.0, or a spec such as 17 or latest that resolves to the newest one published for your platform.

Choosing a version

Minimal, small downloads

Minimal binaries with just what a server needs, much smaller than the official downloads. Downloaded once, checked against the published SHA-256, and shared by every project on the machine.

Downloads and cache

Every platform

Windows x64, Linux x64 and arm64 with glibc or musl (Alpine), macOS x64 and arm64. The library picks the right binaries.

Requirements

Keep a server around

A named instance keeps its data between runs, and a second process or the pgembed CLI attaches to it in milliseconds instead of starting another.

Named instances

Extensions

The extensions bundled with Postgres, plus extension archives the library downloads, verifies and installs for you.

Extensions

Made for tests

One server per test class or assembly with an xUnit fixture, a cache step for CI, and no Postgres left behind when a test run ends.
