Security is paramount in database management. If you are an SQL Server expert looking to learn PostgreSQL, you'll need to understand how PostgreSQL's security model differs from SQL Server's. This talk will compare the security models of the two database systems. Aimed at database administrators and developers, the talk will highlight the key differences in how these systems handle user authentication, roles, and permissions.

For example, did you know that:
-SQL Server distinguishes between logins and users, whereas PostgreSQL uses a unified role-based system for authentication and authorization.
-SQL Server offers predefined server and database roles, such as sysadmin, which provides a range of out-of-the-box permissions. Conversely, PostgreSQL includes default roles like pg_read_all_data, designed to simplify standard permission sets.
-SQL Server allows the creation of custom roles with flexible permission assignments. PostgreSQL's roles enable inheriting permissions from other roles and support complex role hierarchies.

Understanding these differences and others covered during the session will help you understand the security model differences between SQL Server and PostgreSQL, enabling you to implement security best practices effectively in either environment.
