| 2 | Understanding | When we say about handling of MySQL it is much complicated then MySQL. | When we say about handling of PostgreSQL it is easier then MySQL. |
| 3 | Type of Database | When we say about the type of databse in MySQL it prefer a relational database system. | When we say about the type of databse in PostgreSQL it uses as object-relational database system. |
| 4 | Data Replication | When we say about the MySQL has master standby replication. | PostgreSQL enables master standby capabilities with WAL operations. |
| 5 | Use of XML | In MySQL we cannot use XML. | In PostgreSQL we can use XML. |
| 6 | Heavy Datasets | When we say about Huge Datasets we can use OLAP/OLTP operations. | PostgreSQL is perfect choice for data science and machine learning. |
| 7 | Security Option | When we say about the Secuirty option in MYSQL we can use access control security performance. | When we say about PostgreSQL SE-PostgreSQL extension for PostgreSQL adds extra security restrictions based on the SELinux security strategy. |
| 8 | BackUP | MySQL will not offers backup. | PostgreSQL will offer online backup. |
| 9 | Benefit | MySQL helpfull for both large and small projects. | When we say benefits of PostgreSQL it is an extensive database management system, it is well suited to complex queries. |
| 10 | Disadvantages | When we say about one disadvantage or drawback of MYSQL it has a very limited security benefits. | PostgreSQL requires a steep learning curve and little community assistance. |
| 11 | Trobleshoot | MySQL has very vast and simple as it has a friendly and helpful community. | Troubleshoot in PostgreSQL is very complex when we compare this with MySQL. |
| 12 | Licence | MySQL has licence under MIT. | There is no licence fees so no risk of over deployment. |
| 13 | Support of JSON | Both of these supports JSON for storing and transporting data. | PostgreSQL supports JSONB in a binary form of JSON which eliminates duplication keys and unnecessary whitespace. |
| 14 | Syntax | It is similar to SQL language and syntax. | This is based on SQL standard. |
| 15 | Programming Language | MySQL will supports different languages like Supports R, PHP, Java and Perl. | PostgreSQL will supports high level languages like Python, Java, Erlang. |
| 16 | Indexing | This includes R-trees and B-trees. | This will includes expression indexes and partial indexes. |
| 17 | Famous Company | Famous company like Netflix, Amazon and Uber. | Famous company using PostgreSQL Apple, Instagram and Cisco |
