@ -110,6 +110,9 @@ notes:
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.
- If you specify PUBLIC as the user, then the privilege changes will apply
to all users. You may not specify password or role_attr_flags when the
PUBLIC user is specified.
requirements: [ psycopg2 ]
