pgpm — a Postgres Package Manager

A modern CLI for modular PostgreSQL development.

pgpm is a focused command-line tool for PostgreSQL database migrations and package management. It provides the core functionality for managing database schemas, migrations, and module dependencies.

✨ Features

• 📦 Postgres Module System — Reusable, composable database packages with dependency management, per-module plans, and versioned releases
• 🔄 Deterministic Migration Engine — Version-controlled, plan-driven deployments with rollback support and idempotent execution enforced by dependency and validation safeguards.
• 📊 Recursive Module Resolution — Recursively resolves database package dependencies (just like npm) from plan files or SQL headers, producing a reproducible cross-module migration graph.
• 🏷️ Tag-Aware Versioning - Deploy to @tags, resolve tags to changes, and reference tags across modules for coordinated releases
• 🐘 Portable Postgres Development — Rely on standard SQL migrations for a workflow that runs anywhere Postgres does.
• 🚀 Turnkey Module-First Workspaces — pgpm init delivers a ready-to-code Postgres workspace with CI/CD, Docker, end-to-end testing, and modern TS tooling.

🚀 Quick Start

Install & Setup

# Install pgpm globally
npm install -g pgpm

# Start local Postgres (via Docker) and export env vars
pgpm docker start
eval "$(pgpm env)"

Tip: Already running Postgres? Skip the Docker step and just export your PG* vars.

Create a Workspace and Install a Package

# 1. Create a workspace
pgpm init workspace
cd my-app

# 2. Create your first module

pgpm install @pgpm/faker

# 4. Deploy everything
pgpm deploy --createdb --database mydb1
psql -d mydb1 -c "SELECT faker.city('MI');"
>  Ann Arbor

💡 Common Workflows

Starting a New Project and Adding a Change

# 1. Create workspace
pgpm init workspace
cd my-app

# 2. Create your first module
pgpm init
cd packages/new-module

# 3. Add some SQL migrations to sql/ directory
pgpm add some_change

# 4. Deploy to database
pgpm deploy --createdb

🧰 Templates, Caching, and Updates

• pgpm init now scaffolds workspaces/modules from https://github.com/constructive-io/pgpm-boilerplates.git using create-gen-app with a one-week cache (stored under ~/.pgpm/cache/repos). Override with --repo, --from-branch, and --template-path, or use a local template path.
• Run pgpm cache clean to wipe the cached boilerplates if you need a fresh pull.
• The CLI performs a lightweight npm version check at most once per week (skipped in CI or when PGPM_SKIP_UPDATE_CHECK is set). Use pgpm update to upgrade to the latest release.

Working with Existing Projects

# 1. Navigate to your module
cd packages/your-module

# 2. Install a package 
pgpm install @pgpm/faker

# 3. Deploy all installed modules
pgpm deploy --createdb --database mydb1
psql -d mydb1 -c "SELECT faker.city('MI');"
>  Ann Arbor

Testing a pgpm module in a workspace

# 1. Install workspace dependencies
pnpm install

# 2. Enter the packages/<yourmodule>
cd packages/yourmodule

# 3. Test the module in watch mode
pnpm test:watch

# Verify specific package
pgpm verify --package mypackage

pgpm revert

Safely revert database changes.

# Revert latest changes
