-# PostgreSQL Client Authentication Configuration File
-# ===================================================
-#
-# Refer to the "Client Authentication" section in the PostgreSQL
-# documentation for a complete description of this file.  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  [OPTIONS]
-# host          DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
-# hostssl       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
-# hostnossl     DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
-# hostgssenc    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
-# hostnogssenc  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
-#
-# (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
-# non-SSL TCP/IP socket.  Similarly, "hostgssenc" uses a
-# GSSAPI-encrypted TCP/IP socket, while "hostnogssenc" uses a
-# non-GSSAPI socket.
-#
-# DATABASE can be "all", "sameuser", "samerole", "replication", a
-# database name, or a comma-separated list thereof. The "all"
-# keyword does not match "replication". Access to replication
-# must be enabled in a separate record (see example below).
-#
-# 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.
-#
-# ADDRESS specifies the set of hosts the record matches.  It can be a
-# host name, or 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.  A host name
-# that starts with a dot (.) matches a suffix of the actual host name.
-# Alternatively, you can write an IP address and netmask in separate
-# columns to specify the set of hosts.  Instead of a CIDR-address, you
-# can write "samehost" to match any of the server's own IP addresses,
-# or "samenet" to match any address in any subnet that the server is
-# directly connected to.
-#
-# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
-# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
-# Note that "password" sends passwords in clear text; "md5" or
-# "scram-sha-256" are preferred since they send encrypted passwords.
-#
-# OPTIONS are a set of options for the authentication in the format
-# NAME=VALUE.  The available options depend on the different
-# authentication methods -- refer to the "Client Authentication"
-# section in the documentation for a list of which options are
-# available for which authentication methods.
-#
-# Database and user names containing spaces, commas, quotes and other
-# special characters must be quoted.  Quoting one of the keywords
-# "all", "sameuser", "samerole" or "replication" 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 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, run "pg_ctl reload",
-# or execute "SELECT pg_reload_conf()".
-#
-# 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.
-
-# CAUTION: Configuring the system for local "trust" authentication
-# allows any local user to connect as any PostgreSQL user, including
-# the database superuser.  If you do not trust all your local users,
-# use another authentication method.
-
-
-# TYPE  DATABASE        USER            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
-# IPv6 local connections:
-host    all             all             ::1/128                 trust
-# Allow replication connections from localhost, by a user with the
-# replication privilege.
