pig is an open-source PostgreSQL (& Extension) Package Manager for mainstream (EL/Debian/Ubuntu) Linux.

Install PostgreSQL 13-17 along with 404 extensions on (amd64 / arm64) with native OS package manager

Blog: The ideal way to deliver PostgreSQL extensions

1 - Why Pig?

Why would we need yet another package manager? especially for Postgres extensions?

Ever wished installing or upgrading PostgreSQL extensions didn’t feel like digging through outdated readmes, cryptic configure scripts, or random GitHub forks & patches? The painful truth is that Postgres’s richness of extension often comes at the cost of complicated setups—especially if you’re juggling multiple distros or CPU architectures.

Enter Pig, a Go-based package manager built to tame Postgres and its ecosystem of 340+ extensions in one fell swoop. TimescaleDB, Citus, PGVector, 20+ Rust extensions, plus every must-have piece to self-host Supabase — Pig’s unified CLI makes them all effortlessly accessible. It cuts out messy source builds and half-baked repos, offering version-aligned RPM/DEB packages that work seamlessly across Debian, Ubuntu, and RedHat flavors, as well as x86 & ARM arch. No guesswork, no drama.

pig

Instead of reinventing the wheel, Pig piggyback your system’s native package manager (APT, YUM, DNF) and follow official PGDG packaging conventions to ensure a glitch-free fit. That means you don’t have to choose between “the right way” and “the quick way”; Pig respects your existing repos, aligns with standard OS best practices, and fits neatly alongside other packages you already use.

Ready to give your Postgres superpowers without the usual hassle? Check out GitHub for documentation, installation steps, and a peek at its massive extension list. Then, watch your local Postgres instance transform into a powerhouse of specialized modules—no black magic is required. If the future of Postgres is unstoppable extensibility, Pig is the genie that helps you unlock it. Honestly, nobody ever complained that they had too many extensions.

2 - Get Started

Get Started with pig, the PostgreSQL extension manager.

Short Version

Install the pig package first, (you can also use the apt / yum or just copy the binary)

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

Then it’s ready to use, assume you want to install the pg_duckdb extension:

$ pig repo add pigsty pgdg -u  # add pgdg & pigsty repo, then update repo cache
$ pig ext install pg17         # install PostgreSQL 17 kernels with native PGDG packages
$ pig ext install pg_duckdb    # install the pg_duckdb extension (for current pg17)

That’s it, All set! Check the advanced usage for details and the full list 400+ available extensions.

Installation

The pig util is a standalone go binary with no dependencies. You can install with the script:

curl -fsSL https://repo.pigsty.io/pig | bash   # cloudflare default
curl -fsSL https://repo.pigsty.cc/pig | bash   # mainland china mirror

Or just download and extract the binary, or use the apt/dnf package manager:

For Ubuntu 22.04 / 24.04 & Debian 12 or any compatible platforms:

sudo tee /etc/apt/sources.list.d/pigsty.list > /dev/null <<EOF
deb [trusted=yes] https://repo.pigsty.io/apt/infra generic main 
EOF
sudo apt update; sudo apt install -y pig

For EL 8/9 and compatible platforms:

sudo tee /etc/yum.repos.d/pigsty.repo > /dev/null <<-'EOF'
[pigsty-infra]
name=Pigsty Infra for $basearch
baseurl=https://repo.pigsty.io/yum/infra/$basearch
enabled = 1
gpgcheck = 0
module_hotfixes=1
EOF
sudo yum makecache; sudo yum install -y pig

For mainland china user: consider replace the repo.pigsty.io with repo.pigsty.cc

pig has self update feature, you can update pig itself to the latest version with:

pig update

Or if you only want to update the extension catalog, you can fetch the latest catalog with:

pig ext upgrade

4 - Repository Administration

How to manage repositories with pig repo subcommand?

Overview

pig will automatically handle the addition of software repositories for users.

pig repo list                    # available repo list
pig repo info   [repo|module...] # show repo info
pig repo status                  # show current repo status
pig repo add    [repo|module...] # add repo and modules
pig repo rm     [repo|module...] # remove repo & modules
pig repo update                  # update repo pkg cache
pig repo create                  # create repo on current system
pig repo boot                    # boot repo from offline package
pig repo cache                   # cache repo as offline package

Examples

Radical Repo Admin

The default pig repo add pigsty pgdg will add the PGDG repo and PIGSTY repo to your system. While the following command will backup & wipe your existing repo and add all require repo to your system.

pig repo add all --ru        # This will OVERWRITE all existing repo with node,pgdg,pigsty repo

There’s a brutal version of repo add: repo set, which will overwrite you existing repo (-r) by default.

And you can recover you old repos at /etc/apt/backup or /etc/yum.repos.d/backup.

List Repo

You can list all available repo / module (repo collection) with pig repo list:

$ pig repo list

5 - Extension Administration

How to manage repositories with pig ext subcommand?

Overview

pig ext list    [query]       # list & search extension      
pig ext info    [ext...]      # get information of a specific extension
pig ext status  [-v]          # show installed extension and pg status
pig ext add     [ext...]      # install extension for current pg version
pig ext rm      [ext...]      # remove extension for current pg version
pig ext update  [ext...]      # update extension to the latest version
pig ext import  [ext...]      # download extension to local repo
pig ext link    [ext...]      # link postgres installation to path
pig ext upgrade               # fetch the latest extension catalog

Examples

Install PostgreSQL

You can also install PostgreSQL kernel packages with

pig ext install pg17          # install PostgreSQL 17 kernels (all but devel)
pig ext install pg16-simple   # install PostgreSQL 16 kernels with minimal packages
pig ext install pg15 -y       # install PostgreSQL 15 kernels with auto-confirm
pig ext install pg14=14.3     # install PostgreSQL 14 kernels with an specific minor version
pig ext install pg13=13.10    # install PostgreSQL 13 kernels

You can link the installed PostgreSQL to the system path with:

pig ext link pg17             # create /usr/pgsql soft links, and write it to /etc/profile.d/pgsql.sh
. /etc/profile.d/pgsql.sh     # reload the path and take effect immediately

You can also use other package alias, it will translate to corresponding package on your OS distro and the $v will be replaced with the active or given pg version number, such as 17, 16, etc…

pg17:        "postgresql$v postgresql$v-server postgresql$v-libs postgresql$v-contrib postgresql$v-plperl postgresql$v-plpython3 postgresql$v-pltcl postgresql$v-llvmjit",

pig will use the default postgres installation in your active PATH, but you can install extension for a specific installation with -v (when using the PGDG convention), or passing any pg_config path for custom installation.

pig ext install pg_duckdb -v 16     # install the extension for pg16
pig ext install pg_duckdb -p /usr/lib/postgresql/17/bin/pg_config    # specify a pg17 pg_config

Install a specific Version

You can also install PostgreSQL kernel packages with:

pig ext install pgvector=0.7.0 # install pgvector 0.7.0
pig ext install pg16=16.5      # install PostgreSQL 16 with a specific minor version

Beware the APT repo may only have the latest minor version for its software (and require the full version string)

Search Extension

You can perform fuzzy search on extension name, description, and category.

6 - Pigsty Administration

How to manage pigsty with pig sty subcommand?

Overview

The pig can also be used as a cli tool for Pigsty - the battery-include free PostgreSQL RDS. Which brings HA, PITR, Monitoring, IaC, and all the extensions to your PostgreSQL cluster.

pig sty init     # install embed pigsty to ~/pigsty 
pig sty boot     # install ansible and other pre-deps 
pig sty conf     # auto-generate pigsty.yml config file
pig sty install  # run the install.yml playbook

You can use the pig sty subcommand to bootstrap pigsty on current node.

7 - Building Infrastructure

How to setup building infrastructure with pig build subcommand?

Overview

You can build PostgreSQL extension with pig build subcommand, which offers:

pig build repo                   # init build repo (=repo set -ru)
pig build tool  [mini|full|...]  # init build toolset
pig build proxy [user@host:port] # init build proxy (optional)
pig build rust  [-v <pgrx_ver>]  # init rustc & pgrx (0.12.9)
pig build spec                   # init build spec repo
pig build get   [all|std|..]     # get ext code tarball with prefixes
pig build ext   [extname...]     # build extension

Short Version

Prepare building environment

pig build repo
pig build tool
pig build spec
pig build rust

Download extension source tarball

## download big tarball
pig build get std          # download std small tarball
pig build get all          # download all source tarball
pig build get pg_mooncake
pig build get pg_duckdb
pig build get omnigres
pig build get plv8

Build extensions:

pig build ext citus
pig build ext pgjwt

TBD

8 - Compatibility

Linux Distribution compatibility matrix

pig itself runs on any x86_64/aarch64 compatible Linux distribution.

But the pig extension repo only supports the following Linux distributions:

RHEL 8 / 9
Debian 12
Ubuntu 22.04 / 24.04

Code	Distribution	`x86_64`	`aarch64`
el9	RHEL 9 / Rocky9 / Alma9 / …	PG 17 - 13	PG 17 - 13
el8	RHEL 8 / Rocky8 / Alma8 / …	PG 17 - 13	PG 17 - 13
u24	Ubuntu 24.04 (`noble`)	PG 17 - 13	PG 17 - 13
u22	Ubuntu 22.04 (`jammy`)	PG 17 - 13	PG 17 - 13
d12	Debian 12 (`bookworm`)	PG 17 - 13	PG 17 - 13

Here are some bad cases and limitation for above Linux distros:

pg_duckdb el8:*:*
pljava: el8:*:*
pllua: el8:arm:13,14,15
h3: el8.amd.pg17
jdbc_fdw: el:arm:*
pg_partman: u24:*:13
wiltondb: d12:*:*
citus and hydra are mutually exclusive
pg_duckdb will invalidate duckdb_fdw
documentdb_core is not available on arm arch
