community.postgresql.postgresql_ext module – Add or remove PostgreSQL extensions from a database

Note

This module is part of the community.postgresql collection (version 2.1.5).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.postgresql.

To use it in a playbook, specify: community.postgresql.postgresql_ext.

Synopsis

  • Add or remove PostgreSQL extensions from a database.

Requirements

The below requirements are needed on the host that executes this module.

  • psycopg2

Parameters

Parameter

Comments

ca_cert

aliases: ssl_rootcert

string

Specifies the name of a file containing SSL certificate authority (CA) certificate(s).

If the file exists, the server’s certificate will be verified to be signed by one of these authorities.

cascade

boolean

Automatically install/remove any extensions that this extension depends on that are not already installed/removed (supported since PostgreSQL 9.6).

Choices:

  • no ← (default)

  • yes

db

aliases: login_db

string / required

Name of the database to add or remove the extension to/from.

login_host

string

Host running the database.

If you have connection issues when using localhost, try to use 127.0.0.1 instead.

login_password

string

The password this module should use to establish its PostgreSQL session.

login_unix_socket

string

Path to a Unix domain socket for local connections.

login_user

string

The username this module should use to establish its PostgreSQL session.

Default: “postgres”

name

aliases: ext

string / required

Name of the extension to add or remove.

port

aliases: login_port

integer

Database port to connect to.

Default: 5432

schema

string

Name of the schema to add the extension to.

session_role

string

Switch to session_role after connecting.

The specified session_role must be a role that the current login_user is a member of.

Permissions checking for SQL commands is carried out as though the session_role were the one that had logged in originally.

ssl_mode

string

Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server.

See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes.

Default of prefer matches libpq default.

Choices:

  • allow

  • disable

  • prefer ← (default)

  • require

  • verify-ca

  • verify-full

state

string

The database extension state.

Choices:

  • absent

  • present ← (default)

trust_input

boolean

added in 0.2.0 of community.postgresql

If no, check whether values of parameters ext, schema, version, session_role are potentially dangerous.

It makes sense to use no only when SQL injections via the parameters are possible.

Choices:

  • no

  • yes ← (default)

version

string

Extension version to add or update to. Has effect with state=present only.

If not specified and extension is not installed in the database, the latest version available will be created.

If extension is already installed, will update to the given version if a valid update path exists.

Downgrading is only supported if the extension provides a downgrade path otherwise the extension must be removed and a lower version of the extension must be made available.

Set version=latest to always update the extension to the latest available version.

Notes

Note

  • Supports check_mode.

  • The default authentication assumes that you are either logging in as or sudo’ing to the postgres account on the host.

  • This module uses psycopg2, a Python PostgreSQL database adapter.

  • You must ensure that psycopg2 is installed on the host before using this module.

  • If the remote host is the PostgreSQL server (which is the default case), then PostgreSQL must also be installed on the remote host.

  • For Ubuntu-based systems, install the postgresql, libpq-dev, and python-psycopg2 packages on the remote host before using this module.

  • Incomparable versions, for example PostGIS unpackaged, cannot be installed.

  • The default authentication assumes that you are either logging in as or sudo’ing to the postgres account on the host.

  • To avoid “Peer authentication failed for user postgres” error, use postgres user as a become_user.

  • This module uses psycopg2, a Python PostgreSQL database adapter. You must ensure that psycopg2 is installed on the host before using this module.

  • If the remote host is the PostgreSQL server (which is the default case), then PostgreSQL must also be installed on the remote host.

  • For Ubuntu-based systems, install the postgresql, libpq-dev, and python-psycopg2 packages on the remote host before using this module.

  • The ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.

Examples

- name: Adds postgis extension to the database acme in the schema foo
  community.postgresql.postgresql_ext:
    name: postgis
    db: acme
    schema: foo

- name: Removes postgis extension to the database acme
  community.postgresql.postgresql_ext:
    name: postgis
    db: acme
    state: absent

- name: Adds earthdistance extension to the database template1 cascade
  community.postgresql.postgresql_ext:
    name: earthdistance
    db: template1
    cascade: true

# In the example below, if earthdistance extension is installed,
# it will be removed too because it depends on cube:
- name: Removes cube extension from the database acme cascade
  community.postgresql.postgresql_ext:
    name: cube
    db: acme
    cascade: yes
    state: absent

- name: Create extension foo of version 1.2 or update it to that version if it's already created and a valid update path exists
  community.postgresql.postgresql_ext:
    db: acme
    name: foo
    version: 1.2

- name: Create the latest available version of extension foo. If already installed, update it to the latest version
  community.postgresql.postgresql_ext:
    db: acme
    name: foo
    version: latest
