Difference between MySQL and PostgreSQL

A database is a collection of information that is structured in such a way that it is easy to manage and update. To make this task easier various Database Management Systems(DBMS) have been created. These include MySQL, PostgreSQL, MongoDB, Redis etc. 

1. MySQL

It is one of the most famous, open-source Relational database management systems (RDMS). The data in this table is stored in tables which makes it easy to perform CRUD operations (Create, Read, Update and Delete). Some of the features of MySQL are: 

• Fast, easy, and reliable.
• Can be used for both large and small applications.
• Provides high scalability

2. PostgreSQL: 

It is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability.PostgreSQL was the first DBMS that implemented the multi-version concurrency control (MVCC) feature. Some of the highlights of PostgreSQL are:  

• Support for the vast amount of languages.
• It provides advanced security features.
• It has geo-tagging support.

Difference between MySQL and PostgreSQL:  

S.NO.	MySQL	PostgreSQL
1.	It is the most popular Database.	It is the most advanced Database.
2.	It is a relational-based DBMS.	It is an object-based relational DBMS
3.	It is an ACID-compliant only when used with InnoDB and NDB cluster engines	It is an ACID-compliant from the ground up.
4.	The implementation language is C/C++.	The implementation language is C.
5.	It supports the CASCADE option.	CASCADE option is supported.
6.	GUI tool provided is MySQL Workbench	PgAdmin is provided
7.	It does not support partial, bitmap, and expression indexes.	It supports all of these
8.	It doesn’t provide support for Materialised views and Table inheritance.	PostgreSQL provides both of them.
9.	SQL only supports Standard data types.	It supports Advanced data types such as arrays, hstore, and user-defined types.
10.	SQL provides limited MVCC support ( in InnoDB)	Full MVCC support.
11.	It was developed in 1995 by a Swedish company named MySQL AB.	It was developed at the University of California, Department of Computer Science.
12.	It is reliable, simple, and faster.	It is slower and more complex.
13.	Troubleshooting MySQL is easy.	It is difficult to troubleshoot PostgreSQL.
14.	MySQL is licensed beneath GNU GPU.	PostgreSQL is licensed beneath MIT style.
15.	It is best suitable for simple operations like write and reading.	It is commonly used for large and complex operations.
16.	In MySQL, every connection created is an OS thread.	In PostgreSQL, every connection created is an OS process.
