string

added in community.postgresql 3.3.0

Sets a comment on the schema.

To reset the comment, pass an empty string.

Any additional parameters to be passed to libpg.

These parameters take precedence.

Default: {}

database

aliases: db, login_db

string

Name of the database to connect to and add or remove the schema.

Default: "postgres"

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: ""

Default: ""

port

aliases: login_port

integer

Database port to connect to.

Default: 5432

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_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"

  • "prefer" ← (default)

  • "require"

  • "verify-ca"

  • "verify-full"

state

string

The schema state.

Choices:

  • "absent"

  • "present" ← (default)

trust_input

boolean

added in community.postgresql 0.2.0

If false, check whether values of parameters schema, owner, session_role are potentially dangerous.

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

Choices:

  • false

  • true ← (default)

Attributes

Support

Description

check_mode

Support: full

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

Notes

Note

  • 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.
