Pigsty v3.0: Pluggable Kernels & 340 Extensions

GitHub Release | Release Note

Highlights

#

Extension Explosion:

Pigsty v3 ships an unprecedented 340 available PostgreSQL extensions. This includes 121 extension RPM packages and 133 DEB packages — more than the total extension count in the official PGDG repositories (135 RPM / 109 DEB). Moreover, Pigsty cross-ports EL-exclusive and Debian-exclusive extensions, achieving full ecosystem parity between the two major Linux families.

Pluggable Kernels:

Pigsty v3 lets you swap out the PostgreSQL kernel. Current options include SQL Server-compatible Babelfish (wire-protocol-level emulation), Oracle-compatible IvorySQL, and PolarDB (the PostgreSQL RAC). Self-hosted Supabase is also now available on Debian systems. You can run production-grade PostgreSQL clusters with HA, IaC, PITR, and full observability while emulating MSSQL (via WiltonDB), Oracle (via IvorySQL), Oracle RAC (via PolarDB), MongoDB (via FerretDB), or Firebase (via Supabase).

Pro Edition:

We now offer Pigsty Pro Professional Edition, providing value-added services on top of the open-source version. Pro includes additional modules: MSSQL, Oracle, Mongo, K8S, Victoria, Kafka, TigerBeetle, and more, with broader support for PG major versions, operating systems, and chip architectures. It provides precision-tuned offline packages for every OS minor version, plus support for legacy systems like EL7, Debian 11, and Ubuntu 20.04. Pro also offers customizable kernel support with native deployment, monitoring, and management for PolarDB PG/Oracle to meet localization requirements.

Quick Install:

curl -fsSL https://repo.pigsty.cc/get | bash
cd ~/pigsty; ./bootstrap; ./configure; ./install.yml

Breaking Changes

#

This Pigsty release bumps from 2.x to 3.0, introducing several breaking changes:

• Primary OS support shifts to: EL 8 / EL 9 / Debian 12 / Ubuntu 22.04

  • EL7 / Debian 11 / Ubuntu 20.04 are now deprecated and no longer supported
  • Users requiring these systems should consider our subscription service

• Default installation is now online; offline packages are no longer provided, resolving OS minor version compatibility issues.

  • The bootstrap process no longer prompts for offline package download, but will still auto-use one if /tmp/pkg.tgz exists.
  • For offline installation needs, build your own packages or consider our subscription service

• Pigsty upstream repositories have been consolidated, addresses changed, with GPG signing and verification for all packages

  • Standard repo: https://repo.pigsty.io/{apt/yum}
  • China mirror: https://repo.pigsty.cc/{apt/yum}

• API parameter changes and config template updates

  • EL and Debian config templates are now unified, with OS-specific parameters managed in roles/node_id/vars/.
  • Config directory restructured: all templates now in conf/, organized into default, dbms, demo, build categories.

Other Features

#

• Epic OLAP enhancement: DuckDB 1.0.0, DuckDB FDW, PG Lakehouse, and Hydra ported to Debian.
• Vector search and FTS improvements: Vectorscale brings DiskANN vector indexing, Hunspell dictionary support, pg_search 0.9.1.
• Helped ParadeDB resolve package build issues — this extension is now available on Debian/Ubuntu.
• All Supabase-required extensions now available on Debian/Ubuntu; Supabase can now self-host on all supported OSes.
• Scenario-based extension stacks: if you’re unsure which extensions to install, we’ve prepared recommended bundles for specific use cases.
• Complete metadata tables, docs, indexes, and name mappings for all PostgreSQL ecosystem extensions, aligned across EL and Debian.
• Enhanced proxy_env parameter to address DockerHub access issues, with simplified configuration.
• Built a dedicated new repository providing all extensions for PostgreSQL 12-17, with PG16 extensions enabled by default in Pigsty.
• Upgraded existing repos with standard GPG signing and verification. APT repos now use standard layout built with reprepro.
• Sandbox environments for 1, 2, 3, 4, and 43 nodes: meta, dual, trio, full, prod, plus quick config templates for 7 major OS distros.
• PG Exporter adds PostgreSQL 17 and pgBouncer 1.23 metric collectors, with corresponding Grafana panels.
• Monitoring dashboard fixes, added log dashboards for PGSQL Pgbouncer and PGSQL Patroni panels.
• New cache.yml Ansible playbook replaces the old bin/cache and bin/release-pkg scripts for offline package creation.

API Changes

#

• New parameter option: pg_mode now supports pgsql, citus, gpsql, mssql, ivory, polar for specifying PostgreSQL cluster mode
  • pgsql: Standard PostgreSQL HA cluster
  • citus: Citus distributed PostgreSQL native HA cluster
  • gpsql: Monitoring for Greenplum and GP-compatible databases (Pro)
  • mssql: Install WiltonDB/Babelfish, providing Microsoft SQL Server compatibility mode with wire-protocol support, extensions unavailable
  • ivory: Install IvorySQL for Oracle-compatible PostgreSQL HA cluster with Oracle syntax/datatypes/functions/stored procedures, extensions unavailable (Pro)
  • polar: Install PolarDB for PostgreSQL (PG RAC) open-source version for localized database support, extensions unavailable (Pro)
• New parameter: pg_parameters for instance-level postgresql.auto.conf overrides, enabling per-instance customization.
• New parameter: pg_files for copying additional files to PGDATA, designed for commercial PostgreSQL forks requiring license files.
• New parameter: repo_extra_packages for specifying additional packages to download, works with repo_packages for OS-specific extension lists.
• Parameter rename: patroni_citus_db renamed to pg_primary_db for specifying the primary database in a cluster (used in Citus mode)
• Enhanced proxy_env: Proxy server config now written to Docker Daemon for network access; configure -x auto-writes current environment proxy settings.
• Enhanced repo_url_packages: repo.pigsty.io auto-replaces with repo.pigsty.cc when region is China; can now specify downloaded filenames.
• Enhanced pg_databases.extensions: The extension field now supports both dictionary and string modes; dictionary mode provides version support for installing specific extension versions.
• Enhanced repo_upstream: If not explicitly overridden, defaults are extracted from repo_upstream_default in rpm.yml or deb.yml.
• Enhanced repo_packages: If not explicitly overridden, defaults are extracted from repo_packages_default in the corresponding OS vars file.
• Enhanced infra_packages: If not explicitly overridden, defaults are extracted from infra_packages_default in the corresponding OS vars file.
• Enhanced node_default_packages: If not explicitly overridden, defaults are extracted from node_packages_default in the corresponding OS vars file.
• Enhanced pg_packages and pg_extensions: Extensions now undergo lookup and translation from pg_package_map in the corresponding OS vars file.
• Enhanced node_packages and pg_extensions: Packages are upgraded to latest version during installation; node_packages default now includes [openssh-server] to help fix OpenSSH CVE
• Enhanced pg_dbsu_uid: Auto-adjusts to 26 (EL) or 543 (Debian) based on OS type, avoiding manual adjustment.
• Bootstrap logic change: No longer downloads offline packages; added -k|--keep flag to preserve existing package sources during local ansible installation.
• Configure: Removed -m|--mode parameter; use -m|--conf to specify config file, -x|--proxy for proxy config; no longer attempts to fix local SSH issues.
• pgbouncer defaults: max_prepared_statements = 128 enables prepared statement support in transaction pooling mode; server_lifetime set to 600.
• Patroni template defaults: Increased max_worker_processes by +8, raised max_wal_senders and max_replication_slots to 50, increased OLAP template temp file limit to 1/5 of main disk.
