postgresql_privs – Grant or revoke privileges on PostgreSQL database objects¶
Synopsis¶
- Grant or revoke privileges on PostgreSQL database objects.
- This module is basically a wrapper around most of the functionality of PostgreSQL’s GRANT and REVOKE statements with detection of changes (GRANT/REVOKE privs ON type objs TO/FROM roles).
Parameters¶
Notes¶
Note
- Parameters that accept comma separated lists (privs, objs, roles) have singular alias names (priv, obj, role).
- To revoke only
GRANT OPTIONfor a specific object, set state topresentand grant_option tono(see examples). - Note that when revoking privileges from a role R, this role may still have access via privileges granted to any role R is a member of including
PUBLIC. - Note that when revoking privileges from a role R, you do so as the user specified via login. If R has been granted the same privileges by another user also, R can still access database objects via these privileges.
- When revoking privileges,
RESTRICTis assumed (see PostgreSQL docs). - The default authentication assumes that you are either logging in as or sudo’ing to the
postgresaccount 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.
