+# Installation et configuration de Postgresql
+
+[TOC]
+
+## Documentation
+
+### Postgresql :
+* [Postgresql Official Documentation](https://www.postgresql.org/docs/) (EN)
+* [Postgresql Documentation Officielle](https://docs.postgresql.fr/) (FR)
+
+### Modules Ansible :
+* [Ansible Galaxy : Postgresql](https://galaxy.ansible.com/ui/repo/published/community/postgresql/) (EN)
+
+## Configuration
+
+### Variables
+* postgresql_monitoring_(user/password) : Identifiants liés à la supervision et à pmm.
+* postgresql_admin_role_attr_flags : Liste des rôles qu'on souhaite attribuer aux administrateurs. Défaut : CREATEDB,CREATEROLE,NOSUPERUSER.
+* postgresql_pmm_server : Adresse du serveur PMM.
+* postgresql_pmm_server_(username/password) : Identifiants utilisés pour se connecter au serveur PMM.
+* postgresql_pmm_client_(username/password) : Identifiants utilisés pour se connecter au serveur Postgresql local.
+* postgresql_users_networks : Liste des réseaux qui seront ajoutés au fichier pg_hba.conf pour les utilisateurs.
+* postgresql_databases : Liste des bases de données à créer.
+```
+postgresql_databases:
+    - name: "testsla"
+      (optional) owner: "testsla"
+      schemas:
+        - name: "testsla_schema"
+          owner: "testsla"
+
+### Tags
+* install : Installe Postgresql et ses dépendances.
+* config : Gère les configurations, créer les utilisateurs et effectue les tâches liées au monitoring.
+* backup : Installe les composants nécessaires aux sauvegardes.
+* monitoring : Installe et configure pmm-client.
+* databases : Créer les bases de données et leur schémas.
+
+## Fonctionnement du rôle
+
+### Basique pour comprendre Postgresql
+
+#### Rôles, utilisateurs et permissions
+* Un utilisateur correspond à un rôle avec un droit de login.
+* Tous les utilisateurs font partie du groupe "public".
+
+#### Base de données, schémas et tables.
+* Une base de données contient un ou plusieurs schémas qui contiennent une ou plusieurs tables.
+* Les bases de données contiennent par défaut un schema "public" sur lequel le groupe "public" a les droits de lecture.
