Installation Comparison (PostgreSQL vs SQL Server)

SQL Server has multiple editions - Express, Developer, and Enterprise. Express edition is limited with some hardware limits. Most of its use is intended for learning purposes. In the case of the developer edition, it has everything you can get in the enterprise edition. Moreover, the only thing missing is the commercial edition.

PostgreSQL has open source and EDB commercial editions. From the official site, you would be able to use the open-source edition. This edition is free to use for both personal and commercial use cases.

PostgreSQL is similar to SQL Server it can be used for both commercial and private projects. There is no license and per CPU and RAM limit. You'd have some of the performance difference in comparison with the SQL Server but you get much better performance and support for that price.

Maintenance and Upgrade Costs (PostgreSQL vs SQL Server)

PostgreSQL is a free database, and everything it offers is freely accessible. You can download and use it as you please. However, you must hire external support and developers for any extension or technical help. So the cost would vary in the freelance market space. Your upgrade and maintenance costs would be a lot cheaper in comparison.

SQL Server is a premium database. It has multiple editions that you can use for your use case. However, you have to pay for its premium features. You would also have to hire the developers and the support people, which is an additional cost. All of this would add up to increasing your upgrade and maintenance costs.

Reporting Tools

SQL Server has the reporting tool called "SQL Server Reporting Service". This service is available for all the editions of the SQL Server. The tool is easy to use with the "SQL Server Management Studio". This reporting output can be used for development with the Visual Studio too.

PostgreSQL has the PgAdmin tool. The tool allows the reporting and the GUI features which would allow the reporting, data visualization and other editing features. For PostgreSQL database, the enterprise version has it's own reporting service and tools too.

Which Should You Choose?

PostgreSQL and MS SQL Server are both famous, usable, and in-demand databases in the market. Which one suits your needs? Which is easier for you to use? Which is a lot easier to maintain? Which is cheaper to upgrade and maintain?

A lot of these questions would decide the direction of your database purchase. Most freelancers and Linux users choose the PostgreSQL database for most of their operations.
