Pglayers packages PostgreSQL extensions as stackable Docker layers

Pglayers is an open‑source project that targets PostgreSQL extension deployment. It packages each extension as a separate Docker layer. The layers are designed to be stackable, allowing multiple extensions to be combined. This approach simplifies building custom PostgreSQL images. Developers can add or remove extensions without rebuilding the entire image. The project is hosted on GitHub for community contributions. It aims to streamline CI/CD pipelines that rely on PostgreSQL. Users can leverage the tool to accelerate database setup in container environments.
