Security and roles v5.6

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.

• Roles introduces the roles that PGD predefines for controlling access to PGD functionality.

• Role management discusses how roles are managed on multi-database nodes and new nodes.

• PGD predefined roles details the specific privileges of the PGD roles.

• Roles and replication explains how PGD replication interacts with roles and privileges.

• Access control explains how tables, functions, catalog objects and triggers interact with PGD roles and Postgres attributes.
