+# pgpool Client Authentication Configuration File
+# ===============================================
+#
+# 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         127.0.0.1/32          trust
+host    all         all         ::1/128               trust
+host	all	    all		172.20.0.0/24	      trust
