PostgreSQL is an open-source relational data management system (RDBMS). In recent years, there has been a significant increase in popularity as many developers and companies migrate their data from other databases to PostgreSQL.

Although it is daunting to move one database to another database, especially from one database management system to another, the possibilities offered by the transferred target database make the data transfer process more attractive.   Export Data from Oracle to PostgreSQL
• PostgreSQL is open source, although it provides an application API to communicate with both the Oracle and PostgreSQL database. This allows developers to directly access any PostgreSQL component by including the header file in their project.
• Oracle has a built-in authentication system. Postgre, on the other hand, relies on host-based authentication and can therefore support a wide variety of authentication methods. This provides more flexibility for authentication and options to authorize the transaction.
• Oracle often has a proprietary plugin system. However, PostgreSQL's extension system is supported by the general community. Therefore, access to thousands of add-ons is available.
• Oracle has a built-in programming language called PL / SQL, while PostgreSQL includes many of them, not just PL / pgSQL. In addition, PostgreSQL has an extension system that allows users to create additional procedural languages and contexts for further programming as add-ons.
• Performance-wise, PostgreSQL can create an unlimited number of nodes in a headset and offers a custom read operation for different workloads at zero cost. Oracle, on the other hand, is recommended for highly scaled workloads but is very costly.
