New in version 2.8.


Synopsis

Requirements

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

  • psycopg2

Parameters

Parameter Choices/Defaults Comments

ca_cert

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.


aliases: ssl_rootcert

db

string

Name of database to connect to and run queries against.


aliases: login_db

location

path

Path to the tablespace directory in the file system.

Ensure that the location exists and has right privileges.


aliases: path

login_host

string

Host running the database.

login_password

string

The password used to authenticate with.

login_unix_socket

string

Path to a Unix domain socket for local connections.

login_user

string

Default:

"postgres"

The username used to authenticate with.

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

integer

Default:

5432

Database port to connect to.


aliases: login_port

rename_to

-

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.

When reset is passed as an option's value, if the option was set previously, it will be removed https://www.postgresql.org/docs/current/sql-altertablespace.html.

ssl_mode

string

  • allow
  • disable
  • prefer

  • require
  • verify-ca
  • verify-full

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.

state

string

  • absent
  • present

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.

tablespace

string / required

Name of the tablespace to add or remove.


aliases: name



Notes

Note

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

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


Examples

- name: Create a new tablespace called acme and set bob as an its owner
  postgresql_tablespace:
    name: acme
    owner: bob
    location: /data/foo

- name: Create a new tablespace called bar with tablespace options
  postgresql_tablespace:
    name: bar
    set:
      random_page_cost: 1
      seq_page_cost: 1

- name: Reset random_page_cost option
  postgresql_tablespace:
    name: bar
    set:
      random_page_cost: reset

- name: Rename the tablespace from bar to pcie_ssd
  postgresql_tablespace:
    name: bar
    rename_to: pcie_ssd

- name: Drop tablespace called bloat
  postgresql_tablespace:
    name: bloat
    state: absent
