MySQL is developed with a focus on speed. PostgreSQL is developed with a focus on features and standards. It has the complete support of ACID-compliant. MySQL has a multi-layer structure having a set of storage engines. PostgreSQL is a unified database server having a single storage engine. MySQL is popular among developers because of its fast speed and ease of use. PostgreSQL is popular among the developers who come from the Oracle or SQL Server background. It is pronounced as post gress queue ell. It is license under the GNU (General Public License). It was released as Postgre95 in May 1995. It is the most popular database among the organization. MySQL is known for its fast speed, but it is less featured than PostgreSQL. It is described as the most advanced open-source database version of Oracle in the world. PostgreSQL is a more densely featured database system. It is an open-source, cross-platform relational database management system built by Swedish Company MYSQL AB and currently supported by the Oracle. PostgreSQL is an open-source, cross-platform, and object-relational database management system (ORDBMS) built in the computer science department, University of California. Although PostgreSQL and MySQL both are top-rated relational database management systems (RDBMS), but there are radical differences between them. Let us compare both databases through the tabular form. MySQL supports many Operating Systems like Windows, Linux, MacOS, etc. It is developed and supported by the Swedish Company, MySQL AB, and written in C and C++ programming languages. It works as Client-Server Architecture, where the clients make requests through a graphical user interface (GUI), and the server will give the desired output as soon as the instructions are matched. It is commonly used with PHP scripts for creating powerful and dynamic server-side or web-based enterprise applications. It is fast, scalable, and easy to use database management systems in comparison with other databases. Oracle provides support to access and manage this database. MySQL is an open-source and popular database management system used for managing the relational database. It has MVCC (multi-version concurrency control) that allows several users to work on the system at once. It is ACID-compliant, highly concurrent, and also supports functions, stored procedures & triggers. It offers data to store securely and can recover whenever the request is processed. It has supported both SQL and NoSQL query languages. It provides a very easy setup and installation. Initially, it was introduced in the department of computer science, University of California. PostgreSQL is an open-source, cross-platform, and object-relational database management system (ORDBMS), which is officially written in the C programming language. Before making a comparison, we are going to discuss in brief about these databases. Both databases have their benefits, so the organization's better choice depends on the specific requirements and goals. PostgreSQL and MySQL are both the two most popular and widely used database software that comes as an open-source community. When we are choosing which database software is useful and best for our project, it is essential to make a comparison between the databases. Under certain conditions they can be inlined.Next → ← prev Difference between PostgreSQL and MySQL Table functions (functions that return set of rows or table like in this case) should be called in FROM clause. Note the similarity of the two last plans. Test=# explain analyse select * from test_table limit 1000 Versus: test=# explain analyse select * from test(1000) You will see the execution time being far more realistic.Ĭompare: test=# explain analyse select test(1000) However, if you try this query: explain analyse select * from test(10) In this case the planner gets the estimated execution cost of the function, which can be defined in create function. The planner has a problem with your query as it cannot evaluate execution time of the function.
