Puppet module for postgresql
Basic usage
To install the client software
class {'postgresql':  }
To specify a particular version
class {'postgresql':
    version => '9.1',
}
To install the server
class {'postgresql::server': }
By default, the system-wide locale is assumed to be en_US.UTF-8. If the locale is not installed or available, you can specify an alternative:
class { 'postgresql::server':
    locale => 'es_ES.UTF-8',
}
Again, a particular version
class {'postgresql::server':
	version => '9.1',
}
Listen on a specific post / IP address
class {'postgresql::server':
	listen => ['192.168.0.1', ],
	port   => 5432,
}
To allow a remote host to connect to the server, now that you are listening on the Internet.
class {'postgresql::server':
    listen => ['192.168.0.1', ],
    port   => 5432,
    acl   => ['host all all 192.168.0.2/32 md5', ],
}
Refer to the pg_hba.conf docs for the specifics of what each possible ACL field can be set to.
To create a database owned by a user
postgresql::db { 'myuser':
    password => 'mypassword',
}
This will create myuser and then create a database called myuser
which will owned by myuser. You can override the default locale and
encoding and, if required, specify a different owner. For example:
postgresql::db { 'mydatabase':
    owner    => 'myuser',
    password => 'mypassword',
    locale   => 'en_AU.UTF-8',
    encoding => 'C',
}
Read on, if your specific setup does not fall within this (admittedly simple) framework.
Create a user
This creates a role in the database cluster, by default the user is able to login and will inherit the permissions of any groups it is a member of.
pg_user {'pguser':
	ensure   => present,
	password => 'pgpassword',
}
You can also modify other attributes like whether the user can create
databases (createdb), create other roles (createrole) or is the
superuser (superuser).
For example:
pg_user {'mighty_pguser':
    ensure     => present,
    password   => 'themightyone',
    createdb   => true,
    createrole => true,
}
Create a database
This creates a database and adds a dependancy relationship to the user
pg_database {'pgdb':
	ensure   => present,
	owner    => 'pguser',
	require  => Pg_user['pguser'],
}
The default is UTF-8 and en_US.UTF-8 , for English. If required, you can also specify both the locale and encoding of a database.
pg_database {'pgdb':
	ensure   => present,
	owner    => 'pguser',
	encoding => 'UTF8',
	locale   => 'de_DE.UTF-8',
	require  => Pg_user['pguser'],
}
Notes
This module will not (yet) update either the user or database once they have
been initially created. i.e. changing the login permission of a user does not work.
Nor does changing the locale of an existing database.
