community.postgresql.postgresql_owner module – Change an owner of PostgreSQL database object

Note

This module is part of the community.postgresql collection (version 2.3.1).

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_owner.

Synopsis

  • Change an owner of PostgreSQL database object.

  • Also allows to reassign the ownership of database objects owned by a database role to another role.

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.

fail_on_role

boolean

If true, fail when reassign_owned_by role does not exist. Otherwise just warn and continue.

Mutually exclusive with obj_name and obj_type.

Choices:

  • false

  • true ← (default)

login_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

string

Path to a Unix domain socket for local connections.

Default: ""

login_user

string

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

Default: "postgres"

new_owner

string / required

Role (user/group) to set as an obj_name owner.

obj_name

string

Name of a database object to change ownership.

Mutually exclusive with reassign_owned_by.

obj_type

aliases: type

string

Type of a database object.

Mutually exclusive with reassign_owned_by.

Choices:

  • "database"

  • "function"

  • "matview"

  • "sequence"

  • "schema"

  • "table"

  • "tablespace"

  • "view"

port

aliases: login_port

integer

Database port to connect to.

Default: 5432

reassign_owned_by

list / elements=string

Caution - the ownership of all the objects within the specified db, owned by this role(s) will be reassigned to new_owner.

REASSIGN OWNED is often used to prepare for the removal of one or more roles.

REASSIGN OWNED does not affect objects within other databases.

Execute this command in each database that contains objects owned by a role that is to be removed.

If role(s) exists, always returns changed True.

Cannot reassign ownership of objects that are required by the database system.

Mutually exclusive with obj_type.

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"

trust_input

boolean

added in community.postgresql 0.2.0

If false, check whether values of parameters new_owner, obj_name, reassign_owned_by, session_role are potentially dangerous.

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

Choices:

  • false

  • true ← (default)

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.

  • 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.
