# 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 seven forms:
#
# local DATABASE USER METHOD [OPTION]
# host DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# host DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
#
# (The uppercase quantities should 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", "samegroup", a database name (or
# a comma-separated list thereof), or a file name prefixed with "@".
# USER can be "all", an actual user name or a group name prefixed with
# "+", an include file prefixed with "@" or a list containing either.
# IP-ADDRESS and IP-MASK specify the set of hosts the record matches.
# CIDR-MASK is an integer between 0 and 32 (IPv6) or 128(IPv6)
# inclusive, that specifies the number of significant bits in the
# mask, so an IPv4 CIDR-MASK of 8 is equivalent to an IP-MASK of
# 255.0.0.0, and an IPv6 CIDR-MASK of 64 is equivalent to an IP-MASK
# of ffff:ffff:ffff:ffff::. METHOD can be "trust", "reject", "md5",
# "crypt", "password", "krb5", "ident", or "pam". Note that
# "password" uses clear-text passwords; "md5" is preferred for
# encrypted passwords. OPTION is the ident map or the name of the PAM
# service.
#
# INCLUDE FILES:
# If you use include files for users and/or databases (see PostgreSQL
# documentation, section 19.1), these files must be placed in the
# database directory. Usually this is /var/lib/postgres/data/, but
# that can be changed in /etc/postgresql/postmaster.conf with the
# POSTGRES_DATA variable. Putting them in /etc/postgresql/ will NOT
# work since the configuration files are only symlinked from
# POSTGRES_DATA.
#
# 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, or use
# "pg_ctl reload".
#
# Upstream default configuration
#
# The following configuration is the upstream default, which allows
# unrestricted access to amy database by any user on the local machine.
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
#
local all all trust
# IPv4-style local connections:
host all all 127.0.0.1 255.255.255.255 trust
# IPv6-style local connections:
#
# Put your actual configuration here
# ----------------------------------
#
# This default configuration allows any local user to connect as himself
# without a password, either through a Unix socket or through TCP/IP; users
# on other machines are denied access.
#
# If you want to allow non-local connections, you need to add more
# "host" records before the final line that rejects all TCP/IP connections.
# Also, remember TCP/IP connections are only enabled if you enable
# "tcpip_socket" in /etc/postgresql/postgresql.conf.
#
# DO NOT DISABLE!
# If you change this first entry you will need to make sure the postgres user
# can access the database using some other method. The postgres user needs
# non-interactive access to all databases during automatic maintenance
# (see the vacuum command and the /usr/lib/postgresql/bin/do.maintenance
# script).
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
# Database administrative login by UNIX sockets
local all postgres ident
sameuser
#
# All other connections by UNIX sockets
local all all ident
sameuser
#
# All IPv4 connections from localhost
host all all 127.0.0.1 255.255.255.255 ident
sameuser
#
# All IPv6 localhost connections
host all all ::1
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff ident sameuser
host all all ::ffff:127.0.0.1/128 ident
sameuser
#
# reject all other connection attempts
host all all 0.0.0.0 0.0.0.0 reject
