Feature Request: PGXN-ready Artifact Generation in cargo pgrx package

[Nirajkashyap]

PGXN Packaging Support for pgrx

Overview

This proposal adds support in pgrx to generate a PGXN-ready distributable artifact directly from the packaging command.

With a dedicated flag, cargo pgrx package will:

• Generate a valid META.json (PGXN metadata) from Cargo.toml file OR use existing META.json file present in root folder in PGRX extension.
• Bundle the extension into a .zip or .tar.gz archive
• Produce an artifact ready for upload to PGXN

---

Motivation

Publishing a pgrx extension to PGXN currently requires several manual steps:

1. Creating a meta.json
2. Packaging files into the correct archive layout

Automating this workflow will:

• Reduce friction for extension authors
• Ensure consistent packaging
• Simplify release automation (CI/CD)
• Encourage more PGXN adoption

Proposed Usage

cargo pgrx package --pgxn --format zip
