PostgreSQL manages database access permissions using the concept of roles. A role can be either a database user or a group of database users, depending on how the role is set up. Roles can own the database objects and assign privileges on those objects to other roles to control who has access to which objects.

In simpler terms, logical replication in PostgreSQL is a way to copy data from one database to another in a more flexible and customizable manner compared to physical replication.
