community.postgresql.postgresql_publication module – Add, update, or remove PostgreSQL publication

Note

This module is part of the community.postgresql collection (version 3.4.0).

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_publication.

Synopsis

  • psycopg2 >= 2.5.1

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.

cascade

boolean

Drop publication dependencies. Has effect with state=absent only.

Choices:

  • false ← (default)

  • true

comment

string

added in community.postgresql 3.3.0

Sets a comment on the publication.

To reset the comment, pass an empty string.

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 the database to connect to and where the publication state will be changed.

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"

name

string / required

Name of the publication to add, update, or remove.

owner

string

Publication owner.

If owner is not defined, the owner will be set as login_user or session_role.

parameters

dictionary

Dictionary with optional publication parameters.

Available parameters depend on PostgreSQL version.

port

aliases: login_port

integer

Database port to connect to.

Default: 5432

session_role

string

added in community.postgresql 0.2.0

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_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

The publication state.

Choices:

  • "absent"

  • "present" ← (default)

tables

list / elements=string

List of tables to add to the publication.

If no value is set all tables are targeted.

If the publication already exists for specific tables and tables is not passed, nothing will be changed.

If you need to add all tables to the publication with the same name, drop existent and create new without passing tables.

trust_input

boolean

added in community.postgresql 0.2.0

If false, check whether values of parameters name, tables, owner, session_role, params 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: full

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

Notes

Note

  • PostgreSQL version must be 10 or greater.

  • 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 psycopg, a Python PostgreSQL database adapter. You must ensure that psycopg2 >= 2.5.1 or psycopg3 >= 3.1.8 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 python3-psycopg2 packages on the remote host before using this module.
