Difference Between PostgreSQL vs SQLite
In PostgreSQL vs SQLite, SQLite is defined as an open-source relational database management system that is a file-based system popular for its reliability, portability, strong performance, and lightweight on nature that supports low-memory environment also and it provides several features like transactional serverless that supports transaction when any system crashes or power outage goes down. PostgreSQL is another open-source relational database management system used to handle multiple tasks simultaneously and also supports ACID (atomicity, consistency, integrity, and durability) theorem. PostgreSQL is not so popular compared to SQLite and it is not used widely for storing the data.

Key differences of PostgreSQL vs SQLite
Below are the key differences between PostgreSQL and SQLite
One of the major differences between both the system is in-memory capabilities. The SQLite system supports in-memory capabilities that help to perform the data operations efficiently whereas in the PostgreSQL system there is no such functionality of in-memory capability.
The other difference between the PostgreSQL system and the SQLite system is partitioning methods. The SQLite system does not support any type of partitioning methods. On the other hand, the PostgreSQL system supports various types of partitioning methods like list, range, and hash.
One of the major differences between both the system is the use of servers. The SQLite system does not need any kind of server to run thus it is known as serverless. On the other hand, the PostgreSQL system require the server to run and support multiple operating systems like FreeBSD, Windows, Solaris, and many more. The SQLite system does not support XML format. The PostgreSQL system supports XML format.
The other major difference between both the system is authentication and security. The PostgreSQL system provides various advanced security features and there are several in-built configurations. On the other hand, in the SQLite system, there is no authentication system used as the files of a database can be accessed by everyone.

Another difference between these two systems is user management. In the PostgreSQL system, multiple users can access the system with proper authorization. The SQLite system does not support access to multiple users as the user management functionality is not present in the SQLite system. The features offered by the PostgreSQL function are advanced in nature while on the other hand, the SQLite system provides basic features to the user.
The other key difference between the SQLite system and the PostgreSQL system is the replication strategy. The PostgreSQL system supports master-slave replication, streaming, cascading, and synchronous replications. On the other hand, in the SQLite system, there is no replication strategy follow that creates a limitation for this type of system. The compatibility with data types is another major factor in comparing both the system. The PostgreSQL system is mostly compatible with all the data types that make the system popular while on other hand, the SQLite system does not support advanced data types and supports only a few data types like Integer, Real, Blob, Text and Null.
The other major difference between the system is the use of the database. The PostgreSQL system provides the functionality to handle the complex database without having any type of restrictions. On the other hand, the SQLite system is a small application and used to handle a simple database system. The major use of the PostgreSQL system is when the two functions of data integrity and data reliability are the points of concern. On the other hand, the SQLite system is preferred when there is a requirement to use the database is standalone applications.

| Definition | PostgreSQL is an object-oriented relational database management system that is very much compatible with SQL features. The PostgreSQL system persists different properties like atomicity, consistency, integrity, and durability. The system also supports joins, views, foreign keys, stored procedures, and triggers. | The SQLite is an embedded system that follows a relational database management system. The system supports cross-platform supports which means it supports various platforms. The SQLite does not need any type of configuration and supports a transactional database engine. |
| Developed and released | The PostgreSQL system is developed by the PostgreSQL global development group. The PostgreSQL system was released in the year 1996. | The SQLite system is developed by Dwayne Richard Hipp. The SQLite system was released in the year 2000. |
| Programming language used | The programming language used for the development of the PostgreSQL system is C. | The programming language used for the development of the SQLite system is ANSI-C. |
| Programming language | The programming language supported by the PostgreSQL system is C, C++, .Net, Java, Python, Perl, PHP, and JavaScript. | The programming language supported by the SQLite system is C, C++, Java, Python, Perl, Ruby, C#, Scala, and many more languages.
|
| Platform supported | The PostgreSQL system supports multiple platforms like Linux, Unix, Windows, NetBSD, HP-UX, Solaris, OpenBSD. The PostgreSQL system supports user-defined functions. | The primary system supported by the SQLite system is UNIX, Android, Mac-OS, Linux, Windows. The SQLite system does not support server-side scripting. |
| Ease to setup | The installation process of the PostgreSQL system is easy and provides advanced features to the system. The configuration of this system takes time and is a complex part. | The installation process of the SQLite system is easy and the system is easy to use that can be used by the beginner. The system does not need any type of configuration. |
| Features | There are several features supported by the PostgreSQL system like: The system is free to download and the system is extensible in nature. The system supports multiple programming languages. SQL features are supported by the PostgreSQL system. | There are several features supported by the SQLite system like: It is available as open-source and does not require any type of license in it and is flexible in nature. The SQLite supports a cross-platform that helps the user to install this system in any type of operating system. The data stored in this system can be easily fetched and managed. |
Conclusion
The SQLite and PostgreSQL database system is an open-source RDBMS system that supports the ACID theorem and helps to manage the data. The SQLite is preferred in the case of IoT and embedded applications where the PostgreSQL system is preferred for the complex database systems. The selection of the system is based on the use case and requirements of the application.
