## 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 | 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. 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_mode
string

Choices:
- 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

Choices:
- 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 ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.

        name: acme
        owner: bob
        location: /data/foo

      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

## Return Values

Common return values are documented here, the following are the fields unique to this module:

options dictionary | always | Tablespace options. Sample: {'random_page_cost': 1, 'seq_page_cost': 1}
owner string | always | Tablespace owner. Sample: Bob
queries string | always | List of queries that was tried to be executed. Sample: ["CREATE TABLESPACE bar LOCATION '/incredible/ssd'"]
state string | always | Tablespace state at the end of execution. Sample: present
