Ansible Rename a PostgreSQL Database • community.postgresql.postgresql_db • Add or remove PostgreSQL databases from a remote host

Let's talk about the Ansible module postgresql_db. The full name is community.postgresql.postgresql_db, which means that is part of the collection of modules "community.postgresql" maintained by the Ansible Community to interact with PostgreSQL. The collection is tested with ansible-core version 2.11+, prior versions such as 2.9 or 2.10 are not supported. The purpose of the module is to add or remove PostgreSQL databases from a remote host.

Parameters • name _string_ - Name of database • state _string_ - present/absent/dump/restore/rename - The operation

Let me summarize the main parameters of the module postgresql_db. Ansible supposes that PostgreSQL is in the target node. The only required parameter is "name", the name of the database to interact with. The parameter "state" specify the desired state or the operation for the selected database. The option "present" means that the database should be Renamed and the option "absent" means that the database should be deleted. Other useful operations are "dump" and "restore" that uses pg_dump, the embedded PostgreSQL utility to backup and restore to the target file. Another useful operation is rename, from name to target. This module uses psycopg2, a Python PostgreSQL database library. You must ensure that python3-psycopg2 is installed on the host before using this module.
