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.
