+## PostgreSQL Ansible role [](https://travis-ci.org/trainline-eu/postgresql)
+
+Ansible role which installs and configures PostgreSQL clusters, databases and users.
+
+#### Installation
+
+This role has been tested on Ansible 2.3.0 and higher.
+
+To install:
+
+```
+ansible-galaxy install trainline-eu.postgresql
+```
+
+
+#### Dependencies
+
+No dependencies
+
+Recommended dependencies:
+- trainline-eu.barman
+
+#### Compatibility matrix
+
+This table lists the tested version of OS/PostgreSQL couples.
+
+| Distribution / PostgreSQL | 9.1 | 9.4 | 9.5 | 9.6 | 10 | 11 |
+| ------------------------- |:---:|:---:|:---:|:---:|:---:|:---:|
+| Debian 8.x | :no_entry: :white_check_mark:| :white_check_mark:| :white_check_mark:| :white_check_mark:| :white_check_mark:| :grey_question:|
+| Debian 9.x | :no_entry: :white_check_mark:| :white_check_mark:| :white_check_mark:| :white_check_mark:| :white_check_mark:| :grey_question:|
+
+- :white_check_mark: - tested, works fine
+- :grey_question: - will work in the future (help out if you can)
+- :interrobang: - maybe works, not tested
+- :no_entry: - PostgreSQL has reached EOL
+
+
+#### Variables
+
+```yaml

+```
+
+#### Testing
+
+This project comes with a `test/main.yml` testing playbook. It uses `Docker` to provision containers locally and sets up a 3 node postgresql cluster with a barman server.
+
+Coverage of this playbook is probably not complete but at least it's there.
+
+If you are contributing, please first test your changes in a new playbook in the `test/` directory within docker containers, (using the targeted distribution), and if possible, ensure your change is covered in the tests found in [.travis.yml](./.travis.yml).

+# PostgreSQL Client Authentication Configuration File
+# ===================================================
+#
+# Refer to the "Client Authentication" section in the PostgreSQL
+# documentation for a complete description of this file. 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 these forms:
+#
+# local DATABASE USER METHOD [OPTIONS]
+# host DATABASE USER ADDRESS METHOD [OPTIONS]
+# hostssl DATABASE USER ADDRESS METHOD [OPTIONS]
+# hostnossl DATABASE USER ADDRESS METHOD [OPTIONS]
+#
+# (The uppercase items must 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", "samerole", "replication", a
+# database name, or a comma-separated list thereof. 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. In that case you will also need to make PostgreSQL
+# listen on a non-local interface via the listen_addresses
+# configuration parameter, or via the -i or -h command line switches.
+
+
+
+
+# DO NOT DISABLE!
+# If you change this first entry you will need to make sure that the
+# database superuser can access the database using some other method.
+# Noninteractive access to all databases is required during automatic
+# maintenance (custom daily cronjobs, replication, and similar tasks).
+#
+# Database administrative login by Unix domain socket
+local all postgres peer
+
+# TYPE DATABASE USER ADDRESS METHOD
+
+# "local" is for Unix domain socket connections only
+local all all peer
+# IPv4 local connections:
+host all all 127.0.0.1/32 md5
+{% for host in postgres_allowed_hosts %}
+host all {{ host.user }} {{ host.range }} md5
+{% endfor %}
+
+# IPv6 local connections:
+host all all ::1/128 md5
+# Allow replication connections from localhost, by a user with the
+# replication privilege.
+#local replication postgres peer
+#host replication postgres 127.0.0.1/32 md5
+#host replication postgres ::1/128 md5
+{% for host in postgres_replication_hosts %}
+hostssl replication {{ host.user }} {{ host.range }} md5

+# The commented-out settings shown in this file represent the default values.
+# Re-commenting a setting is NOT sufficient to revert it to the default value;

+# This file is read on server startup and when the server receives a SIGHUP

+# server for the changes to take effect, or use "pg_ctl reload". Some
+# parameters, which are marked below, require a server shutdown and restart to
+# take effect.

+# Any parameter can also be given as a command-line option to the server, e.g.,
