PostgreSQL and MySQL compared

PostgreSQL and MySQL are both relational database management systems, but they have some key differences.

PostgreSQL is an open-source, advanced, and powerful Object-Relational Database Management System (ORDBMS) while MySQL is a Relational Database Management System (RDBMS).

PostgreSQL is known for its robust feature set, which includes support for advanced data types, such as arrays, hstore (a key-value store), and JSON. It also supports advanced indexing and full-text search capabilities. PostgreSQL also supports stored procedures, triggers, and views.

MySQL, on the other hand, is known for its ease of use and high performance. It is a popular choice for web-based applications and is often used in conjunction with PHP. MySQL is generally considered to be less powerful than PostgreSQL in terms of advanced data types and indexing capabilities, but it is still a solid choice for many applications.

In terms of licensing, PostgreSQL is released under the PostgreSQL License, which is a permissive open-source license and MySQL is released under the GNU General Public License, which is a more restrictive open-source license.

Overall, PostgreSQL is a more powerful and feature-rich database management system, while MySQL is more lightweight and easy to use.
