PostgreSQL is one of many popular relational databases, known for its reliability, extensibility, and robust feature set, making it a preferred choice for many. When working with PostgreSQL, grasping the database schema is equal to understanding its architecture. Therefore, the significance of proficient schema-management skills cannot be overestimated. In this article, we will talk about one fundamental operation beneficial for database managers: schema listing.

What is PostgreSQL schema?

In PostgreSQL, a schema serves as a logical container, grouping related database objects together within a designated namespace: tables, views, functions, you name it. By default, every PostgreSQL database contains a schema named public, but you can create as many of those as you wish for better object organization. The role of schemas in PostgreSQL database architecture is quite versatile as they significantly improve numerous aspects of your day-to-day work:

• Modularity and scalability
• Data organization and readability
• Access control and permissions management
• Multi-tenancy and application isolation
• Schema-level backups and restores
