PIG Package Manager

— Postgres Install Genius, the missing extension package manager for the PostgreSQL ecosystem

PIG is a command-line tool specifically designed for installing, managing, and building PostgreSQL and its extensions. Developed in Go, it is ready to use out of the box, simple, and lightweight (4MB). PIG is not a reinvented wheel, but rather a PiggyBack - a high-level abstraction layer that leverages existing Linux distribution package managers (apt/dnf). It abstracts away the differences between operating systems, chip architectures, and PG major versions, allowing you to install and manage PG kernels and 444+ extensions with just a few simple commands.

PIG is also automation-friendly by design: consistent parameter styles, clear error messages, and safe guards like --dry-run for high-risk operations.

Please note: for extension installation, pig is not a mandatory component. You can still use apt/dnf package managers to directly access the Pigsty PGSQL repository.

Quick Start

Use the following command to install PIG on your system:

Default Installation (Cloudflare CDN):

curl -fsSL https://repo.pigsty.io/pig | bash

China Mirror:

curl -fsSL https://repo.pigsty.cc/pig | bash

After installation, you can get started with just a few commands. For example, to install PG 18 and the pg_duckdb extension:

$ pig repo set                        # One-time setup for Linux, Pigsty + PGDG repos (overwrites!)
$ pig install pg18                    # Install PostgreSQL 18 kernel (native PGDG packages)
$ pig install pg_duckdb -v 18         # Install pg_duckdb extension (for PG 18)
$ pig install -y postgis timescaledb  # Install multiple extensions for current active PG version
$ pig install -y vector               # You can use extension name (vector) or package name (pgvector)!
