# risotto.postgresql - Configure the PostgreSQL server

PostgreSQL is the World's Most Advanced Open Source Relational Database.
This collection allows you to configure a PostgreSQL server and create user
accounts.

## Usage
### Example playbook with Rougail
Add to your structural file something like:
```yaml
%YAML 1.2
---
version: 1.1
my_postgresql:
type: postgresql
my_accounts:
type: accounts
...
```
> [!NOTE]
>
> Do not forget to add Rougail structural file as Rougail types.
For example you can add an YAML user data with something like:
```yaml
---
my_accounts:
remotes: # PostgreSQL client address
- example.net
remote_example_net: # Account for example.net
database: example # PostgreSQL database name for example.net
username: username # PostgreSQL username for example.net
password: secrets # PostgreSQL password for example.net
```
Add to your playbook:
```yaml
---
- name: Configure the PostgreSQL server
hosts: servers
vars:
postgresql: '{{ my_postgresql }}'
accounts: '{{ my_accounts }}'
roles:
- role: risotto.postgresql
```
### Example playbook without Rougail
> [!NOTE]
>
> The variables will not be properly validated without Rougail.
```yaml
---
- name: Configure the PostgreSQL server
hosts: servers
vars:
accounts:
remotes: # PostgreSQL client address
- example.net
remote_example_net: # Account for example.net
database: example # PostgreSQL database name for example.net
username: username # PostgreSQL username for example.net
password: secrets # PostgreSQL password for example.net
roles:
- role: risotto.postgresql
```

# PostgreSQL User Name Maps
# =========================
#
# Refer to the PostgreSQL documentation, chapter "Client
# Authentication" for a complete description. A short synopsis
# follows.
#
# This file controls PostgreSQL user name mapping. It maps external
# user names to their corresponding PostgreSQL user names. Records
# are of the form:
#
# MAPNAME SYSTEM-USERNAME PG-USERNAME
#
# (The uppercase quantities must be replaced by actual values.)
#
# MAPNAME is the (otherwise freely chosen) map name that was used in
# pg_hba.conf. SYSTEM-USERNAME is the detected user name of the
# client. PG-USERNAME is the requested PostgreSQL user name. The
# existence of a record specifies that SYSTEM-USERNAME may connect as
# PG-USERNAME.
#
# If SYSTEM-USERNAME starts with a slash (/), it will be treated as a
# regular expression. Optionally this can contain a capture (a
# parenthesized subexpression). The substring matching the capture
# will be substituted for \1 (backslash-one) if present in
# PG-USERNAME.
#
# Multiple maps may be specified in this file and used by pg_hba.conf.
#
# No map names are defined in the default configuration. If all
# system user names and PostgreSQL user names are the same, you don't
# need anything in this file.
#
# 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
# ----------------------------------
# MAPNAME SYSTEM-USERNAME PG-USERNAME

# 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]
# hostgssenc DATABASE USER ADDRESS METHOD [OPTIONS]
# hostnogssenc 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 a TCP/IP socket (encrypted or not)
# - "hostssl" is a TCP/IP socket that is SSL-encrypted
# - "hostnossl" is a TCP/IP socket that is not SSL-encrypted
# - "hostgssenc" is a TCP/IP socket that is GSSAPI-encrypted
# - "hostnogssenc" is a TCP/IP socket that is not GSSAPI-encrypted
#
# 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", "scram-sha-256",
# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
# Note that "password" sends passwords in clear text; "md5" or
# "scram-sha-256" are preferred since they send 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 server receives a
# SIGHUP signal. If you edit the file on a running system, you have to
# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
# or execute "SELECT pg_reload_conf()".
#
# 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.
