Highlight Features

Extension Exploding:

Pigsty now has an unprecedented 340 available extensions for PostgreSQL. This includes 121 extension RPM packages and 133 DEB packages, surpassing the total number of extensions provided by the PGDG official repository (135 RPM/109 DEB). Pigsty has ported unique PG extensions from the EL/DEB system to each other, achieving a great alignment of extension ecosystems between the two major distributions.

A crude list of the extension ecosystem is as follows:

Plugable Kernels:

Pigsty v3 allows you to replace the PostgreSQL kernel, currently supporting Babelfish (SQL Server compatible, with wire protocol emulation), IvorySQL (Oracle compatible), and RAC PolarDB for PostgreSQL. Additionally, self-hosted Supabase is now available on Debian systems. You can emulate MSSQL (via WiltonDB), Oracle (via IvorySQL), Oracle RAC (via PolarDB), MongoDB (via FerretDB), and Firebase (via Supabase) in Pigsty with production-grade PostgreSQL clusters featuring HA, IaC, PITR, and monitoring.

Pro Edition:

We now offer PGSTY Pro, a professional edition that provides value-added services on top of the open-source features. The professional edition includes additional modules: MSSQL, Oracle, Mongo, K8S, Victoria, Kafka, etc., and offers broader support for PG major versions, operating systems, and chip architectures. It provides offline installation packages customized for precise minor versions of all operating systems, and support for legacy systems like EL7, Debian 11, Ubuntu 20.04.

  • EL7 / Debian 11 / Ubuntu 20.04 systems are now deprecated and no longer supported.
  • Users needing to run on these systems should consider our subscription service.
• Default to online installation, offline packages are no longer provided to resolve minor OS version compatibility issues.
  • The bootstrap process will no longer prompt for downloading offline packages, but if /tmp/pkg.tgz exists, it will still use the offline package automatically.
  • For offline installation needs, please create offline packages yourself or consider our subscription service.
• Unified adjustment of upstream software repositories used by Pigsty, address changes, and GPG signing and verification for all packages.
  • Standard repository: https://repo.pigsty.io/{apt/yum}
  • Domestic mirror: https://repo.pigsty.cc/{apt/yum}
• API parameter changes and configuration template changes
  • Configuration templates for EL and Debian systems are now consolidated, with differing parameters managed in the roles/node_id/vars/ directory.
  • Configuration directory changes, all configuration file templates are now placed in the conf directory and categorized into default, dbms, demo, build.
• Docker is now completely treated as a separate module, and will not be downloaded by default

• New parameter: repo_extra_packages, used to specify additional packages to download, to be used in conjunction with repo_packages, facilitating the specification of extension lists unique to OS versions.
• Parameter renaming: patroni_citus_db renamed to pg_primary_db, used to specify the primary database in the cluster (used in Citus mode).
• Parameter enhancement: Proxy server configurations in proxy_env will be written to the Docker Daemon to address internet access issues, and the configure -x option will automatically write the proxy server configuration of the current environment.
• Parameter enhancement: Allow using path item in infra_portal entries, to expose local dir as web service rather than proxy to another upstream.

• Parameter enhancement: If the repo_packages parameter is not explicitly overridden, it will extract the default value for the corresponding system from rpm.yml or deb.yml.
• Parameter enhancement: If the infra_packages parameter is not explicitly overridden, it will extract the default value for the corresponding system from rpm.yml or deb.yml.
• Parameter enhancement: If the node_default_packages parameter is not explicitly overridden, it will extract the default value for the corresponding system from rpm.yml or deb.yml.
• Parameter enhancement: The extensions specified in pg_packages and pg_extensions will now perform a lookup and translation from the pg_package_map defined in rpm.yml or deb.yml.
• Parameter enhancement: Packages specified in node_packages and pg_extensions will be upgraded to the latest version upon installation. The default value in node_packages is now [openssh-server], helping to fix the OpenSSH CVE.
• Parameter enhancement: pg_dbsu_uid will automatically adjust to 26 (EL) or 543 (Debian) based on the operating system type, avoiding manual adjustments.

How to upgrade from v1.1.1

There’s no API change in 1.2.0 You can still use old pigsty.yml configuration files (PG13).

For the infrastructure part. Re-execution of repo will do most of the parts

As for the database. You can still use the existing PG13 instances. In-place upgrade is quite tricky especially when involving extensions such as PostGIS & Timescale. I would highly recommend performing a database migration with logical replication.

The new playbook pgsql-migration.yml will make this a lot easier. It will create a series of scripts which will help you to migrate your cluster with near-zero downtime.

v1.1.1

• [ENHANCEMENT] replace timescaledb apache version with timescale version
• [ENHANCEMENT] upgrade prometheus to 2.30
• [BUG FIX] now pg_exporter config dir’s owner are {{ pg_dbsu }} instead of prometheus

How to upgrade from v1.1.0 The major change in this release is timescaledb. Which replace old apache license version with timescale license version

stop/pause postgres instance with timescaledb
yum remove -y timescaledb_13
