Build Status

Description

Installs PostgreSQL, The world's most advanced open source database.

This installs postgres 9.x from the PostgreSQL Apt Repository.

Currently supported versions:

The default version is 9.3.

Requirements

Supported Platforms

The following platforms are supported by this cookbook, meaning that the recipes run on these platforms without error:

Recipes

Usage

This cookbook installs the postgresql components if not present, and pulls updates if they are installed on the system.

This cookbook provides three definitions to create, alter, and delete users as well as create and drop databases, or setup extensions. Usage is as follows:

Users

# create a user
pg_user "myuser" do
  privileges superuser: false, createdb: false, login: true
  password "mypassword"
end

# create a user with an MD5-encrypted password
pg_user "myuser" do
  privileges superuser: false, createdb: false, login: true
  encrypted_password "667ff118ef6d196c96313aeaee7da519"
end

# drop a user
pg_user "myuser" do
  action :drop
end

Or add users via attributes:

"postgresql": {
  "users": [
    {
      "username": "dickeyxxx",
      "password": "password",
      "superuser": true,
      "createdb": true,
      "login": true
    }
  ]
}

Databases and Extensions

# create a database
pg_database "mydb" do
  owner "myuser"
  encoding "utf8"
  template "template0"
  locale "en_US.UTF8"
end

# install extensions to database
pg_database_extensions "mydb" do
  languages "plpgsql"              # install `plpgsql` language - single value may be passed without array
  extensions ["hstore", "dblink"]  # install `hstore` and `dblink` extensions - multiple values in array
  postgis true                     # install `postgis` support
end

# drop dblink extension
pg_database_extensions "mydb" do
  action :drop
  extensions "dblink"
end

# drop a database
pg_database "mydb" do
  action :drop
end

Or add the database via attributes:

"postgresql": {
  "databases": [
    {
      "name": "my_db",
      "owner": "dickeyxxx",
      "template": "template0",
      "encoding": "utf8",
      "locale": "en_US.UTF8",
      "extensions": "hstore"
    }
  ]
}

Configuration

The postgresql.conf configuration may be set one of two ways:

To create a custom configuration, set the node["postgresql"]["conf"] hash with your custom settings:

"postgresql": {
  "conf": {
    "data_directory": "/dev/null",
    // ... all options explicitly set here
  }
}

You may also set the contents of pg_hba.conf via attributes:

"postgresql": {
  "pg_hba": [
    { "type": "local", "db": "all", "user": "postgres",   "addr": "",             "method": "ident" },
    { "type": "local", "db": "all", "user": "all",        "addr": "",             "method": "trust" },
    { "type": "host",  "db": "all", "user": "all",        "addr": "127.0.0.1/32", "method": "trust" },
    { "type": "host",  "db": "all", "user": "all",        "addr": "::1/128",      "method": "trust" },
    { "type": "host",  "db": "all", "user": "postgres",   "addr": "127.0.0.1/32", "method": "trust" },
    { "type": "host",  "db": "all", "user": "username",   "addr": "127.0.0.1/32", "method": "trust" }
  ]
}

Change APT distribution

Currently the APT distributions are sourced from http://apt.postgresql.org/pub/repos/apt/. In some cases this source might not immediately contain a package for the distribution of your target system.

The node["postgresql"]["apt_distribution"] attribute can be used to install PostgreSQL from a different compatible distribution:

"postgresql": {
  "apt_distribution": "precise"
}
