PostgreSQL Schema: Learning PostgreSQL with Grant
An important aspect of building and managing a database is organizing the objects within your database. You may have tables that support different functions, for example, a schema for warehousing operations and another for sales. Some logins may need access to some tables, but not others. You might want to isolate one set of objects within a database from other sets of objects. All of this, and more, can be accomplished using schemas within a database and PostgreSQL supports the use of schema for just these types of functions.

PostgreSQL Constraints: Learning PostgreSQL with Grant
One of the most important aspects of data management is the ability to ensure that the data in your database is well defined and consistent. Some aspects of that are ensured through the relational data structures you design. Another piece of control is using the correct data type. Then, we get to constraints. A constraint is a way to validate data prior to adding it to your database. This is one more tool in the toolbox that helps you maintain good data.

PostgreSQL Basics: Roles and Privileges
Information security, whether in databases, applications, or larger IT systems, is based on the principles of Authentication and Authorization, often referred to as AuthN and AuthZ respectively. Likewise, PostgreSQL security involves creating roles that allow access to server resources (AuthN) and then granting privileges to database objects appropriately (AuthZ). Understanding how each of these components work together is essential to effectively manage security in a PostgreSQL cluster.
