Security and roles
==================

EDB Postgres Distributed allows a PGD cluster to be administered without
giving access to the stored data by design. It achieves this through the
use of roles and controlled access to system objects.

-  :ref:`Data conflicts for roles and tablespace differences <Data conflicts for roles and tablespace differences>`  introduces the roles that PGD predefines for
   controlling access to PGD functionality.

-  :ref:`Role management <Role management>`  discusses how roles are managed on multi-database nodes
   and new nodes.

-  :ref:`PGD predefined roles <PGD predefined roles>`  details the specific privileges of the PGD roles.

-  :ref:`Roles and replication <Roles and replication>`  explains how PGD replication interacts with roles and
   privileges.

-  :ref:`Access Control <Access Control>`  explains how tables, functions, catalog objects and
   triggers interact with PGD roles and Postgres attributes.
