Parameters

Parameter

Comments

active

boolean

fast_forward

boolean

If fast_forward is set to True, fast_forward will bypass the query processing layer (rewriting, caching) and pass through the query directly as is to the backend server. If omitted the proxysql database default for fast_forward is False.

Choices:

  • false

  • true

frontend

boolean

If frontend is set to True, this (username, password) pair is used for authenticating to the PostgreSQL servers against any hostgroup.

transaction_persistent

boolean

If this is set for the user with which the PostgreSQL client is connecting to ProxySQL (thus a “frontend” user), transactions started within a hostgroup will remain within that hostgroup regardless of any other rules. If omitted the proxysql database default for transaction_persistent is True.

Choices:

Examples

---
# This example adds a user, it saves the postgresql user config to disk, but
# avoids loading the postgresql user config to runtime (this might be because
# several users are being added and the user wants to push the config to
# runtime in a single batch using the community.general.proxysql_manage_config
# module).  It uses supplied credentials to connect to the proxysql admin
# interface.

- name: Add a user
  community.proxysql.proxysql_pgsql_users:
    login_user: 'admin'
    login_password: 'admin'
    username: 'productiondba'
    state: present
    load_to_runtime: false

# This example removes a user, saves the postgresql user config to disk, and
# dynamically loads the postgresql user config to runtime.  It uses credentials
# in a supplied config file to connect to the proxysql admin interface.

- name: Remove a user
  community.proxysql.proxysql_pgsql_users:
    config_file: '~/proxysql.cnf'
    username: 'postgresboy'
    state: absent
