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# hostgssenc    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
17# hostnogssenc  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
18#
19# (The uppercase items must be replaced by actual values.)
20#
21# The first field is the connection type: "local" is a Unix-domain
22# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
23# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
24# non-SSL TCP/IP socket.  Similarly, "hostgssenc" uses a
25# GSSAPI-encrypted TCP/IP socket, while "hostnogssenc" uses a
26# non-GSSAPI socket.
27#
28# DATABASE can be "all", "sameuser", "samerole", "replication", a
29# database name, or a comma-separated list thereof. The "all"
30# keyword does not match "replication". Access to replication
31# must be enabled in a separate record (see example below).
32#
33# USER can be "all", a user name, a group name prefixed with "+", or a
34# comma-separated list thereof.  In both the DATABASE and USER fields
35# you can also write a file name prefixed with "@" to include names
36# from a separate file.
37#
38# ADDRESS specifies the set of hosts the record matches.  It can be a
39# host name, or it is made up of an IP address and a CIDR mask that is
40# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
41# specifies the number of significant bits in the mask.  A host name
42# that starts with a dot (.) matches a suffix of the actual host name.
43# Alternatively, you can write an IP address and netmask in separate
44# columns to specify the set of hosts.  Instead of a CIDR-address, you
45# can write "samehost" to match any of the server's own IP addresses,
46# or "samenet" to match any address in any subnet that the server is
47# directly connected to.
48#
49# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
50# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
51# Note that "password" sends passwords in clear text; "md5" or
52# "scram-sha-256" are preferred since they send encrypted passwords.
53#
54# OPTIONS are a set of options for the authentication in the format
55# NAME=VALUE.  The available options depend on the different
56# authentication methods -- refer to the "Client Authentication"
57# section in the documentation for a list of which options are
58# available for which authentication methods.
59#
60# Database and user names containing spaces, commas, quotes and other
61# special characters must be quoted.  Quoting one of the keywords
62# "all", "sameuser", "samerole" or "replication" makes the name lose
63# its special character, and just match a database or username with
64# that name.
65#
66# This file is read on server startup and when the server receives a
67# SIGHUP signal.  If you edit the file on a running system, you have to
68# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
69# or execute "SELECT pg_reload_conf()".
70#
71# Put your actual configuration here
72# ----------------------------------
73#
74# If you want to allow non-local connections, you need to add more
75# "host" records.  In that case you will also need to make PostgreSQL
76# listen on a non-local interface via the listen_addresses
77# configuration parameter, or via the -i or -h command line switches.
