-# pgPool-II configuration file a custom version

-# This file consists of lines of the form:

-#   name = value

-# Whitespace may be used.  Comments are introduced with "#" anywhere on a line.
-# The complete list of parameter names and allowed values can be found in the
-# pgPool-II documentation.

-# This file is read on server startup and when the server receives a SIGHUP
-# signal.  If you edit the file on a running system, you have to SIGHUP the
-# server for the changes to take effect, or use "pgpool reload".  Some
-# parameters, which are marked below, require a server shutdown and restart to
-# take effect.

-# pgpool Client Authentication Configuration File a custom version
-# ===============================================
-#
-# The format rule in this file follows the rules in the PostgreSQL
-# Administrator's Guide. Refer to chapter "Client Authentication" for a
-# complete description.  A short synopsis follows.
-#
-# This file controls: which hosts are allowed to connect, how clients
-# are authenticated, which user names they can use, which databases they
-# can access.  Records take one of these forms:
-#
-# local      DATABASE  USER  METHOD  [OPTION]
-# host       DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
-#
-# (The uppercase items must be replaced by actual values.)
-#
-# The first field is the connection type: "local" is a Unix-domain
-# socket, "host" is either a plain or SSL-encrypted TCP/IP socket.
-#
-# DATABASE can be "all", "sameuser", a database name, or a comma-separated
-# list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf
-# file is not supported, since pgpool does not know which group a user
-# belongs to. Also note that the database specified here may not exist in
-# the backend PostgreSQL. pgpool will authenticate based on the database's
-# name, not based on whether it exists or not.
-#
-# USER can be "all", a user name, or a comma-separated list thereof.  In
-# both the DATABASE and USER fields you can also write a file name prefixed
-# with "@" to include names from a separate file. Note that a group name
-# prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported
-# because of the same reason as "samegroup" token. Also note that a user
-# name specified here may not exist in the backend PostgreSQL. pgpool will
-# authenticate based on the user's name, not based on whether he/she exists.
-#
-# CIDR-ADDRESS specifies the set of hosts the record matches.
-# It is made up of an IP address and a CIDR mask that is an integer
-# (between 0 and 32 (IPv4) that specifies the number of significant bits in
-# the mask.  Alternatively, you can write an IP address and netmask in
-# separate columns to specify the set of hosts.
-#
-# METHOD can be "trust", "reject", "md5" or "pam".  Note that "pam" sends passwords
-# in clear text.
-#
-# OPTION is the name of the PAM service. Default service name is "pgpool"
-#
-# Database and user names containing spaces, commas, quotes and other special
-# characters must be quoted. Quoting one of the keywords "all" or "sameuser"
-# makes the name lose its special character, and just match a database or
-# username with that name.
-#
-# This file is read on pgpool startup.  If you edit the file on a running
-# system, you have to restart the pgpool  for the changes to take effect.
-
-# Put your actual configuration here
-# ----------------------------------
-#
-# If you want to allow non-local connections, you need to add more
-# "host" records. In that case you will also need to make pgpool listen
-# on a non-local interface via the listen_addresses configuration parameter.
-#
-
-# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
-
-# "local" is for Unix domain socket connections only
-#local   all         all                               trust
-# IPv4 local connections:
-host    all         all         0.0.0.0/0          md5
