PostgreSQL is indeed an object-relational database, which means that while it's essentially a relational database, it also has features that are more commonly associated with object databases, such as table inheritance and feature overloading.
PostgreSQL, or Postgres, describes itself as "the world's most sophisticated open-source relational database." It was built with the intention of being highly expandable and consistent with industry standards. This ensures that ACID standards are followed while eliminating the requirement to acquire locks. MVCC creates a "Database Snapshot" for each transaction, allowing modifications to be performed without affecting other transactions. PostgreSQL manages concurrency with Multi-Version Concurrency Control (MVCC). PostgreSQL is available for use on a variety of systems, including Windows, Linux, Mac, and UNIX, to mention a few. It also adds a variety of features to RDBMS characteristics, such as indexes, data structures, views, events, and atomicity, to mention a few. PostgreSQL is well-known for its open-source platform, which includes all RDBMS functionality.

The open-source PostgreSQL database is creating a significant dent in Oracle's market share. Oracle Database is Oracle Corporation's commercialized, licensed multi-model database management system, and the nation's biggest relational database management system (RDBMS). SQL is the query language for accessing data in Oracle's relational databases. Since its start, Oracle has positioned itself as being one of the largest RDBMS (Relational Database Management System) manufacturers in the IT market. This open-source database system supports JSON and SQL querying and is the main source of data for a wide range of mobile, internet, spatial information, and analytics applications. PostgreSQL is a SQL-compliant and extensible Object-Relational Database Management System.
