Synopsis

  • Gathers statistics about PostgreSQL user objects.

Requirements

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

  • 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

db

string

Name of database to connect.


aliases: login_db

filter

list / elements=string

Limit the collected information by comma separated string or YAML list.

Allowable values are functions, indexes, tables.

By default, collects all subsets.

Unsupported values are ignored.

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.

port

integer

Default:

5432

Database port to connect to.


aliases: login_port

schema

string

Restrict the output by certain schema.

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_mode

string

  • 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.

trust_input

boolean

added in 0.2.0 of community.postgresql

  • no
  • yes

If no, check the value of session_role is potentially dangerous.

It makes sense to use no only when SQL injections via session_role are possible.



Notes

Note

  • size and total_size returned values are presented in bytes.
  • For tracking function statistics the PostgreSQL track_functions parameter must be enabled. See https://www.postgresql.org/docs/current/runtime-config-statistics.html for more information.
  • 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.
