PostgreSQL Formula

PostgreSQL, often simply Postgres, is an object-relational database management system available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. It is released under the PostgreSQL License, which is an MIT-style license, and is thus free and open source software. PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of volunteers employed and supervised by companies such as Red Hat and EnterpriseDB.

Sample pillars

Single deployment

Single database server with empty database

postgresql:
  server:
    enabled: true
    version: 9.1
    bind:
      address: 127.0.0.1
      port: 5432
      protocol: tcp
    clients:
    - 127.0.0.1
    database:
      name: 'databasename'
      encoding: 'UTF8'
      locale: 'cs_CZ'
      user:
        name: 'username'
        password: 'password'
        host: 'localhost'
        rights: 'all privileges'

Single database server with initial data

postgresql:
  server:
    enabled: true
    version: 9.1

    - 127.0.0.1
    database:
      name: 'databasename'
      encoding: 'UTF8'
      locale: 'cs_CZ'
      initial_data:
        engine: backupninja

Sample usage

Init database cluster with given locale

sudo su - postgres -c "/usr/lib/postgresql/9.3/bin/initdb /var/lib/postgresql/9.3/main --locale=C"

Convert PostgreSQL cluster from 9.1 to 9.3

sudo su - postgres -c '/usr/lib/postgresql/9.3/bin/pg_upgrade -b /usr/lib/postgresql/9.1/bin -B /usr/lib/postgresql/9.3/bin -d /var/lib/postgresql/9.1/main/ -D /var/lib/postgresql/9.3/main/ -O "-c config_file=/etc/postgresql/9.3/main/postgresql.conf" -o "-c config_file=/etc/postgresql/9.1/main/postgresql.conf"'

Ubuntu on 14.04 on some machines won't create default cluster

sudo pg_createcluster 9.3 main --start
