What is PostgreSQL?
PostgreSQL, also known as Postgres, is a free and open-source Database that allows us to work with Relational Databases. It is a row-oriented database and is best suited for transactional workloads. As the name suggests, Postgres emphasizes SQL compliance and is used as the primary Data Store or Data Warehouse by many Web, Mobile, and Analytics Applications. PostgreSQL is completely free for everyone to use and requires little to no maintenance, making it very popular among users all over the world.
PostgreSQL offers all the standard and modern features expected by an Enterprise Transactional Database like unique primary keys, foreign key referential integrity, user-defined types, multi-version concurrency control, etc. It also allows you to store 100s of TBs of data in tables.
PostgreSQL Relational Database System is a powerful and scalable platform based on a Single Server Architecture with no concept of Clusters. It is ACID-compliant and hence it ensures that your transactions are handled in a timely and efficient manner. It supports various types of advanced data types such as UUID, JSON, Network Addresses, Geometric Data, etc. On top of that, Postgres offers high customizability and hence it can readily incorporate new functionalities into its system.

What is DBeaver?
DBeaver is a free, open-source, and multi-platform Database Management/Administration Tool and SQL Client software application for Database Administrators, Developers, and Analysts. Often referred to as a universal Database Tool, DBeaver supports more than 80 Databases (which are both Relational and Non-Relational) including PostgreSQL, MySQL, SQLite, SQL Server, DB2, Sybase, Phoenix, MS Access, Teradata, Apache Hive, etc.
DBeaver uses the JDBC Application Programming Interface (API) to interact with Relational Databases via a JDBC Driver. For Non-Relational and NoSQL Databases, it uses proprietary Database Drivers to interact with them. DBeaver comes in 2 editions: Community and Enterprise. Enterprise Edition supports NoSQL Databases, such as MongoDB and Cassandra, SSH Tunneling, Vector Graphics (SVG), and a few more enterprise-level features.
Key Features of DBeaver
Working with a Database in a GUI Tool is now easy with DBeaver, take a look at some of its promising features.
