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

Note

This module is part of the community.postgresql collection (version 2.4.2).

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

• Add, update, or remove PostgreSQL publication.

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.
cascade boolean	Drop publication dependencies. Has effect with state=absent only. Choices: false ← (default) true
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 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.
