Requirements

  • 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
cascade
boolean
    Choices:
  • no ←
  • yes
Drop publication dependencies. Has effect with state=absent only.
db
string
Name of the database to connect to and where the publication state will be changed.

aliases: login_db
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.
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
integer
Default:
5432
Database port to connect to.

aliases: login_port
session_role
string
added in 0.2.0 of community.general
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
    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 ←
The publication state.
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 0.2.0 of community.general
    Choices:
  • no
  • yes ←
If no, check whether values of parameters name, tables, owner, session_role, params are potentially dangerous.
It makes sense to use no only when SQL injections via the parameters are possible.

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.
