community.postgresql.postgresql_tablespace module – Add or remove PostgreSQL tablespaces from remote hosts

Note

This module is part of the community.postgresql collection (version 2.4.2).

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. You need further requirements to be able to use this module, see Requirements for details.

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

Synopsis

  • Adds or removes PostgreSQL tablespaces from remote hosts.

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.

connect_params

dictionary

added in community.postgresql 2.3.0

Any additional parameters to be passed to libpg.

These parameters take precedence.

Default: {}

db

aliases: login_db

string

Name of database to connect to and run queries against.

location

aliases: path

path

Path to the tablespace directory in the file system.

Ensure that the location exists and has right privileges.

login_host

aliases: host

string

Host running the database.

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

Default: ""

login_password

string

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

Default: ""

login_unix_socket

aliases: unix_socket

string

Path to a Unix domain socket for local connections.

Default: ""

login_user

aliases: login

string

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

Default: "postgres"

owner

string

Name of the role to set as an owner of the tablespace.

If this option is not specified, the tablespace owner is a role that creates the tablespace.

port

aliases: login_port

integer

Database port to connect to.

Default: 5432

rename_to

string

New name of the tablespace.

The new name cannot begin with pg_, as such names are reserved for system tablespaces.

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.

set

dictionary

Dict of tablespace options to set. Supported from PostgreSQL 9.0.

For more information see https://www.postgresql.org/docs/current/sql-createtablespace.html.

When reset is passed as an option’s value, if the option was set previously, it will be removed.

ssl_cert

path

added in community.postgresql 2.4.0

Specifies the file name of the client SSL certificate.

ssl_key

path

added in community.postgresql 2.4.0

Specifies the location for the secret key used for the client certificate.

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

Tablespace state.

state=present implies the tablespace must be created if it doesn’t exist.

state=absent implies the tablespace must be removed if present. state=absent is mutually exclusive with location, owner, i(set).

See the Notes section for information about check mode restrictions.

Choices:

  • "absent"

  • "present" ← (default)

tablespace

aliases: name

string / required

Name of the tablespace to add or remove.

trust_input

boolean

added in community.postgresql 0.2.0

If false, check whether values of parameters tablespace, location, owner, rename_to, session_role, settings_list are potentially dangerous.

It makes sense to use false only when SQL injections via the parameters are possible.

Choices:

  • false

  • true ← (default)

Attributes

Attribute

Support

Description

check_mode

Support: partial

state=absent and state=present (the second one if the tablespace doesn’t exist) do not support check mode because the corresponding PostgreSQL DROP and CREATE TABLESPACE commands can not be run inside the transaction block.

Can run in check_mode and return changed status prediction without modifying target.

Notes

Note

  • 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.
