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
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.
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.
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
trust_input
boolean
added in 0.2.0 of community.postgresql
    Choices:
  • no
  • yes ←
If no, check whether values of parameters tablespace, location, owner, rename_to, session_role, settings_list are potentially dangerous.
It makes sense to use no only when SQL injections via the parameters are possible.

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.
