-# Class: postgresql::config::beforeservice
-#
-# Parameters:
-#
-# [*ip_mask_deny_postgres_user*] - ip mask for denying remote access for postgres user; defaults to '0.0.0.0/0',
-# meaning that all TCP access for postgres user is denied.
-# [*ip_mask_allow_all_users*] - ip mask for allowing remote access for other users (besides postgres);
-# defaults to '127.0.0.1/32', meaning only allow connections from localhost
-# [*listen_addresses*] - what IP address(es) to listen on; comma-separated list of addresses; defaults to
-# 'localhost', '*' = all
-# [*ipv4acls*] - list of strings for access control for connection method, users, databases, IPv4
-# addresses; see postgresql documentation about pg_hba.conf for information
-# [*ipv6acls*] - list of strings for access control for connection method, users, databases, IPv6
-# addresses; see postgresql documentation about pg_hba.conf for information
-# [*pg_hba_conf_path*] - path to pg_hba.conf file
-# [*postgresql_conf_path*] - path to postgresql.conf file
-# [*manage_redhat_firewall*] - boolean indicating whether or not the module should open a port in the firewall on
-# redhat-based systems; this parameter is likely to change in future versions. Possible
-# changes include support for non-RedHat systems and finer-grained control over the
-# firewall rule (currently, it simply opens up the postgres port to all TCP connections).
-# [*manage_pg_hba_conf*] - boolean indicating whether or not the module manages pg_hba.conf file.
-#
-# Actions:
-#
-# Requires:
-#
-# Usage:
-# This class is not intended to be used directly; it is
-# managed by postgresl::config. It contains resources
-# that should be handled *before* the postgres service
-# has been started up.
-#
-# class { 'postgresql::config::before_service':
-# ip_mask_allow_all_users => '0.0.0.0/0',
