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. Exporting Data from MySQL to PostgreSQL

• Although there are many similarities between MySQL and PostgreSQL, there are also radical differences. Currently owned by Oracle, MySQL is an open-source database but also offers several versions for proprietary use. However, PostgreSQL, on the other hand, is a completely free and open-source database and is released under the open-source licensePostgreSQL. In terms of SQL compatibility, while MySQL is compatible with some versions, PostgreSQL provides compatibility to a large extent.
• MySQL does not support materialized views, which are database objects containing the results of a query that can be updated as needed from the actual base table, it only supports temporary tables that store data that does not need to persist after the session that created it. However, PostgreSQL supports both table types.
• Model systems that are extensible by the user in many ways, such as new data types, functions, operators, index methods, and procedural languages are not supported by MySQL. PostgreSQL, on the other hand, has several extensibility-specific features. In this way, it is possible to add new models, functions, index types. Both MySQL and PostgreSQL offer SSL encrypted connections between client and server communication. In addition, PostgreSQL offers an internal enhancement called SE-PostgreSQL that provides additional access controls based on the SELinux security policy.
• MySQL has JSON data type support but no other NoSQLfeatures. It also does not support indexing for JSON. PostgreSQL, on the other hand, supports JSON and native XML support and STORE and other NoSQL features. It also supports the indexing of JSON data for faster access.
