2# PostgreSQL Client Authentication Configuration File
3# ===================================================
4#
5# Refer to the "Client Authentication" section in the PostgreSQL
6# documentation for a complete description of this file. A short
7# synopsis follows.
8#
9# This file controls: which hosts are allowed to connect, how clients
10# are authenticated, which PostgreSQL user names they can use, which
11# databases they can access. Records take one of these forms:
12#
13# local DATABASE USER METHOD [OPTIONS]
14# host DATABASE USER ADDRESS METHOD [OPTIONS]
15# hostssl DATABASE USER ADDRESS METHOD [OPTIONS]
16# hostnossl DATABASE USER ADDRESS METHOD [OPTIONS]
17#
18# (The uppercase items must be replaced by actual values.)
19#
20# The first field is the connection type: "local" is a Unix-domain
21# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
22# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
23# plain TCP/IP socket.
24#
25# DATABASE can be "all", "sameuser", "samerole", "replication", a
26# database name, or a comma-separated list thereof. The "all"
27# keyword does not match "replication". Access to replication
28# must be enabled in a separate record (see example below).
29#
30# USER can be "all", a user name, a group name prefixed with "+", or a
31# comma-separated list thereof. In both the DATABASE and USER fields
32# you can also write a file name prefixed with "@" to include names
33# from a separate file.
34#
35# ADDRESS specifies the set of hosts the record matches. It can be a
36# host name, or it is made up of an IP address and a CIDR mask that is
37# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
38# specifies the number of significant bits in the mask. A host name
39# that starts with a dot (.) matches a suffix of the actual host name.
40# Alternatively, you can write an IP address and netmask in separate
41# columns to specify the set of hosts. Instead of a CIDR-address, you
42# can write "samehost" to match any of the server's own IP addresses,
43# or "samenet" to match any address in any subnet that the server is
44# directly connected to.
45#
46# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
47# "ident", "peer", "pam", "ldap", "radius" or "cert". Note that
48# "password" sends passwords in clear text; "md5" is preferred since
49# it sends encrypted passwords.
50#
51# OPTIONS are a set of options for the authentication in the format
52# NAME=VALUE. The available options depend on the different
53# authentication methods -- refer to the "Client Authentication"
54# section in the documentation for a list of which options are
55# available for which authentication methods.
56#
57# Database and user names containing spaces, commas, quotes and other
58# special characters must be quoted. Quoting one of the keywords
59# "all", "sameuser", "samerole" or "replication" makes the name lose
60# its special character, and just match a database or username with
61# that name.
62#
63# This file is read on server startup and when the postmaster receives
64# a SIGHUP signal. If you edit the file on a running system, you have
65# to SIGHUP the postmaster for the changes to take effect. You can
66# use "pg_ctl reload" to do that.
67
68# Put your actual configuration here
69# ----------------------------------
70#
71# If you want to allow non-local connections, you need to add more
72# "host" records. In that case you will also need to make PostgreSQL
73# listen on a non-local interface via the listen_addresses
74# configuration parameter, or via the -i or -h command line switches.
75
76
77
78
79# DO NOT DISABLE!
80# If you change this first entry you will need to make sure that the
81# database superuser can access the database using some other method.
82# Noninteractive access to all databases is required during automatic
83# maintenance (custom daily cronjobs, replication, and similar tasks).
84#
85# Database administrative login by Unix domain socket
86local all postgres peer
87
88# TYPE DATABASE USER ADDRESS METHOD
89
90# "local" is for Unix domain socket connections only
91local all all peer
92# IPv4 local connections:
93host all all 127.0.0.1/32 md5
94{% for host in postgres_allowed_hosts %}
95host all {{ host.user }} {{ host.range }} md5
96{% endfor %}
97
98# IPv6 local connections:
99host all all ::1/128 md5
100# Allow replication connections from localhost, by a user with the
101# replication privilege.
102#local replication postgres peer
103#host replication postgres 127.0.0.1/32 md5

9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, run "pg_ctl reload", or execute
21# "SELECT pg_reload_conf()". Some parameters, which are marked below,
22# require a server shutdown and restart to take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,

3# PostgreSQL configuration file
4# -----------------------------

6# This file consists of lines of the form:
7#
8# name = value
9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, or use "pg_ctl reload". Some
21# parameters, which are marked below, require a server shutdown and restart to
22# take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,
25# "postgres -c log_connections=on". Some parameters can be changed at run time
26# with the "SET" SQL command.
27#
28# Memory units: kB = kilobytes Time units: ms = milliseconds
29# MB = megabytes s = seconds
30# GB = gigabytes min = minutes

3# PostgreSQL configuration file

6# This file consists of lines of the form:
7#
8# name = value
9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, or use "pg_ctl reload". Some
21# parameters, which are marked below, require a server shutdown and restart to
22# take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,
25# "postgres -c log_connections=on". Some parameters can be changed at run time
26# with the "SET" SQL command.
27#
28# Memory units: kB = kilobytes Time units: ms = milliseconds

6# This file consists of lines of the form:
7#
8# name = value
9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, or use "pg_ctl reload". Some
21# parameters, which are marked below, require a server shutdown and restart to
22# take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,
25# "postgres -c log_connections=on". Some parameters can be changed at run time
26# with the "SET" SQL command.

6# This file consists of lines of the form:

8# name = value
9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, or use "pg_ctl reload". Some
21# parameters, which are marked below, require a server shutdown and restart to
22# take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,
25# "postgres -c log_connections=on". Some parameters can be changed at run time
26# with the "SET" SQL command.
