## Requirements

The below requirements are needed on the host that executes this module.

- psycopg2

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
ca_cert string added in 2.8 |  | 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 added in 2.8 | Choices: no ← yes | Automatically install/remove any extensions that this extension depends on that are not already installed/removed (supported since PostgreSQL 9.6).
db string / required |  | Name of the database to add or remove the extension to/from. aliases: login_db
login_host string |  | Host running the database.
login_password string |  | The password used to authenticate with.
login_unix_socket string added in 2.8 |  | 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 extension to add or remove. aliases: ext
port integer | Default: 5432 | Database port to connect to. aliases: login_port
schema string added in 2.8 |  | Name of the schema to add the extension to.
session_role string added in 2.8 |  | 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 added in 2.8 | 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. See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes. Default of `prefer` matches libpq default.
state string | Choices: absent present ← | The database extension state.

## Notes

Note

- The default authentication assumes that you are either logging in as or sudo’ing to the `postgres` account on the host.
- 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.

## Examples

    - name: Adds postgis extension to the database acme in the schema foo
      postgresql_ext:
        name: postgis
        db: acme
        schema: foo

    - name: Removes postgis extension to the database acme
      postgresql_ext:
        name: postgis
        db: acme
        state: absent

    - name: Adds earthdistance extension to the database template1 cascade
      postgresql_ext:
        name: earthdistance
        db: template1
        cascade: true

    # In the example below, if earthdistance extension is installed,
    # it will be removed too because it depends on cube:
    - name: Removes cube extension from the database acme cascade
      postgresql_ext:
        name: cube
        db: acme
        cascade: yes
        state: absent

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
