module-postgresql/manifests/db.pp

# Define: postgresql::db
#
# This module creates database instances, a user, and grants that user
# privileges to the database.
#
# Since it requires class postgresql::server, we assume to run all commands as the
# postgresql user against the local postgresql server.
#
# TODO: support an array of privileges for "grant"; currently only supports a single
#  privilege, which is pretty useless unless that privilege is "ALL"
#
# Parameters:
#   [*title*]       - postgresql database name.
#   [*user*]        - username to create and grant access.
#   [*password*]    - user's password.  may be md5-encoded, in the format returned by the "postgresql_password"
#                            function in this module
#   [*charset*]     - database charset.
#   [*grant*]       - privilege to grant user.
#
# Actions:
#
# Requires:
#
#   class postgresql::server
#
# Sample Usage:
#
#  postgresql::db { 'mydb':
#    user     => 'my_user',
#    password => 'password',
#    grant    => 'all'
#  }
#
