1# PostgreSQL Client Authentication Configuration File
2# ===================================================
3#
4# Refer to the "Client Authentication" section in the PostgreSQL
5# documentation for a complete description of this file.  A short
6# synopsis follows.
7#
8# This file controls: which hosts are allowed to connect, how clients
9# are authenticated, which PostgreSQL user names they can use, which
10# databases they can access.  Records take one of these forms:
11#
12# local      DATABASE  USER  METHOD  [OPTIONS]
13# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
14# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
15# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
16#
17# (The uppercase items must be replaced by actual values.)
18#
19# The first field is the connection type: "local" is a Unix-domain
20# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
21# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
22# plain TCP/IP socket.
23#
24# DATABASE can be "all", "sameuser", "samerole", "replication", a
25# database name, or a comma-separated list thereof. The "all"
26# keyword does not match "replication". Access to replication
27# must be enabled in a separate record (see example below).
28#
29# USER can be "all", a user name, a group name prefixed with "+", or a
30# comma-separated list thereof.  In both the DATABASE and USER fields
31# you can also write a file name prefixed with "@" to include names
32# from a separate file.
33#
34# ADDRESS specifies the set of hosts the record matches.  It can be a
35# host name, or it is made up of an IP address and a CIDR mask that is
36# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
37# specifies the number of significant bits in the mask.  A host name
38# that starts with a dot (.) matches a suffix of the actual host name.
39# Alternatively, you can write an IP address and netmask in separate
40# columns to specify the set of hosts.  Instead of a CIDR-address, you
41# can write "samehost" to match any of the server's own IP addresses,
42# or "samenet" to match any address in any subnet that the server is
43# directly connected to.
44#
45# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
46# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
47# Note that "password" sends passwords in clear text; "md5" or
48# "scram-sha-256" are preferred since they send encrypted passwords.
49#
50# OPTIONS are a set of options for the authentication in the format
51# NAME=VALUE.  The available options depend on the different
52# authentication methods -- refer to the "Client Authentication"
53# section in the documentation for a list of which options are
54# available for which authentication methods.
55#
56# Database and user names containing spaces, commas, quotes and other
57# special characters must be quoted.  Quoting one of the keywords
58# "all", "sameuser", "samerole" or "replication" makes the name lose
59# its special character, and just match a database or username with
60# that name.
61#
62# This file is read on server startup and when the server receives a
63# SIGHUP signal.  If you edit the file on a running system, you have to
64# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
65# or execute "SELECT pg_reload_conf()".

68# ----------------------------------
69#
70# If you want to allow non-local connections, you need to add more
71# "host" records.  In that case you will also need to make PostgreSQL
72# listen on a non-local interface via the listen_addresses
73# configuration parameter, or via the -i or -h command line switches.
