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", "gss", "sspi", +# "ident", "peer", "pam", "ldap", "radius" or "cert". Note that +# "password" sends passwords in clear text; "md5" is preferred since +# it sends 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 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. You can +# use "pg_ctl reload" to do that. + +# Put your actual configuration here +# ---------------------------------- +# +# If you want to allow non-local connections, you need to add more +# "host" records.
