Pigsty v2.7: Extension Overwhelming

I wrote a popular article last month - Postgres is eating the database world, explaining why extensions matter to the PostgreSQL ecosystem.

Based on this idea, we’ve packaged 20 brand-new extensions in v2.7. With these extensions added, Pigsty offers 157 non-contrib extensions for EL Distros and 116 for Debian/Ubuntu Distros. Combined with 73 built-in Contrib extensions, Pigsty now has a total of 255 unique extensions available, which takes PostgreSQL’s versatility to a whole new level!

Complete list of available extensions: https://pigsty.io/docs/reference/extension/

  • repo_upstream: Adjust according to ubuntu / debian repo.
  • repo_packages: Adjust according to ubuntu / debian naming convention
  • node_repo_local_urls: use the default value: ['deb [trusted=yes] http://${admin_ip}/pigsty ./']
  • node_default_packages
    • zlib -> zlib1g, readline -> libreadline-dev
    • vim-minimal -> vim-tiny, bind-utils -> dnsutils, perf -> linux-tools-generic,

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.

Service

pg_services and pg_services_extra Defines the services in cluster:

A service has some mandatory fields:

  • name: service’s name
  • src_port: which port to listen and expose service?
  • selector: which instances belonging to this service?
  # default service will route {ip|name}:5436 to primary postgres (5436->5432 primary)
  - name: default           # service's actual name is {{ pg_cluster }}-{{ service.name }}
    src_ip: "*"             # service bind ip address, * for all, vip for cluster virtual ip address

Database

Add additional locale support: lc_ctype and lc_collate.

It’s mainly because of pg_trgm ’s weird behavior on i18n characters.

pg_databases:
  - name: meta                      # name is the only required field for a database
    # owner: postgres                 # optional, database owner

  • expire_at and expire_in options
  • pgbouncer option for user is now false by default

Apply Changes

You can create new users on running postgres clusters with pgsql-createuser.yml playbook.

  1. Define your new users in config files (pg_users)
  2. Pass new user.name with option pg_user to playbook.

v0.5.0 Release Note

Pigsty v0.5.0 has significant improvement on database templating

v0.5.0

Pigsty now have an Official Site 🎉 !

New Features

  • Add Database Provision Template
  • Add Init Template
  • Add Business Init Template
  • Refactor HBA Rules variables
  • Fix dashboards bugs.
  • Move pg-cluster-replication to default dashboards
  • Use ZJU PostgreSQL mirror as default to accelerate repo build phase.
  • Move documentation to official site: https://pigsty.cc
  • Download newly created offline installation packages: pkg.tgz (v0.5)

Database Provision Template

Now you can customize your database content with pigsty !

pg_users:
  - username: test
    password: test
    comment: default test user
    groups: [ dbrole_readwrite ]    # dborole_admin|dbrole_readwrite|dbrole_readonly
pg_databases:                       # create a business database 'test'
  - name: test
    extensions: [{name: postgis}]   # create extra extension postgis
    parameters:                     # overwrite database meta's default search_path
      search_path: public,monitor

pg-init-template.sql wil be used as default template1 database init script pg-init-business.sql will be used as default business database init script

you can customize default role system, schemas, extensions, privileges with variables now:
