+# PostgreSQL Client Authentication Configuration File
+# ===================================================
+#
+# Refer to the PostgreSQL Administrator's Guide, 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 PostgreSQL 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]
+# hostssl    DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
+# hostnossl  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, "hostssl" is an
+# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
+#
+# DATABASE can be "all", "sameuser", "samerole", a database name, or
+# a comma-separated list thereof.
+#
+# USER can be "all", a user name, a group name prefixed with "+", 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.
+#
+# 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) or 128 (IPv6) inclusive) 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", "crypt", "password",
+# "krb5", "ident", or "pam".  Note that "password" sends passwords
+# in clear text; "md5" is preferred since it sends encrypted passwords.
+#
+# OPTION is the ident map or the name of the PAM service, depending on METHOD.
+#
+# Database and user names containing spaces, commas, quotes and other special
+# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
+# "samerole" makes the name lose its special character, and just match a
+# database or username with that name.
+#
+# This file is read on server startup and when the postmaster receives
+# a SIGHUP signal.  If you edit the file on a running system, you have
+# to SIGHUP the postmaster for the changes to take effect.  You can use
+# "pg_ctl reload" to do that.
+
+# 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 PostgreSQL listen
+# on a non-local interface via the listen_addresses configuration parameter,
+# or via the -i or -h command line switches.
