Postgres Roles: What to Know Before You Begin

Roles in Postgres are a crucial part of managing access control within the system. Unlike many other systems where users and roles are separate entities, in Postgres, "now there are only roles." This unified approach to roles and users offers excellent flexibility but can also lead to confusion for those coming from systems with more traditional user/group distinctions. Understanding the layered nature of Postgres' privilege system is essential when troubleshooting access issues or planning migrations. Careful planning, regular audits, and following best practices are key to successfully managing roles in Postgres.
