Transactions: PostgreSQL and MySQL InnoDB utilize MVCC (Multi-Version Concurrency Control) to handle concurrent data access.MySQL has recently introduced a new replication model called Group Replication, but it is still a relatively new feature with some limitations. PostgreSQL supports multi-master replication using third-party extensions. Replication: PostgreSQL and MySQL perform master-slave database replication, but the methods and options for replication differ.These provide more options for optimizing query performance and data retrieval. PostgreSQL has a more refined indexing system than MySQL, including support for B-tree, GiST (Generalized Search Tree), and GIN (Generalized Inverted Index) indexes. Indexing: In MySQL, the default index type is B-tree, which is well-suited for most use cases.MySQL, while it has some geospatial support, could be more robust in this area. Geospatial Support: PostgreSQL strongly supports geospatial data, including a rich set of data types, functions, and operators for handling geographic data.Indeed, MySQL's JSON storage is well-suited for simpler JSON structures and straightforward web applications. MySQL's JSON binary storage format can be considered comparable to PostgreSQL's JSONB. On the other hand, MySQL has a more limited set of data types and is geared toward more straightforward web applications. Data Types: PostgreSQL supports a broader range of advanced data types, including arrays, hstore (a key-value store), and JSONB (binary JSON).PostgreSQL and MySQL both offer a wide range of features as relational database management systems, but there are some key differences between the two:

Over time, Oracle acquired the open-source database management system MySQL and turned it into a commercial product. MySQL, on the other hand, was first released in 1995 and has been widely used for web-based applications due to its high performance and ease of use. It is known for its strong adherence to SQL standards, robust feature set, and focus on data integrity and security.

PostgreSQL was first released in 1996 and has become a widely used open-source RDBMS. This article will compare PostgreSQL and MySQL to help you make an informed decision in 2023. However, they have different strengths and weaknesses that make one more suitable for specific use cases. Both have been around for decades and have proven highly reliable, secure, and scalable. Regarding choosing a relational database management system (RDBMS), two popular options are PostgreSQL and MySQL.
