Published

PostgreSQL vs Microsoft SQL Server are both relational databases designed to help businesses store data in a structured manner for querying.  PostgreSQL is an open-source database software, meaning businesses can access its source code for free. Microsoft SQL Server is a relational database software that is most popular with mid-sized and large enterprises.  PostgreSQL is used by businesses of all sizes, though it is more popular with smaller businesses due to its open-source nature. 

Features

PostgreSQL and Microsoft SQL Server both include essential relational database features such as data recovery, but they also have a few standout features that set them apart from each other.

PostgreSQL supports a wide variety of operating systems including Windows, Linux, OS X, and Unix.  Additionally, PostgreSQL is a highly customizable relational database as its open source nature allows skilled development teams to contribute to the code on their own.  Since PostgreSQL is open source, it is also supported by many community developers, so bugs are fixed quickly.

Microsoft SQL Server provides excellent features for Windows ecosystems such as support for C# and Visual Basic.  Additionally, Microsoft SQL Server allows for the automated updating of views as tables change, so users can quickly see the results of data changes.  SQL Server also provides support from the vendor, so businesses that need assistance with implementation may appreciate Microsoft support.

Limitations

PostgreSQL and Microsoft SQL Server both allow for the storage of structured data, but they also have a few limitations that are important to consider.

PostgreSQL supports a wide variety of operating systems, but it doesn’t support languages such as C# and Visual Basic.  Businesses using the Windows operating system and other Microsoft technologies may prefer Microsoft SQL Server.  Additionally, PostgreSQL has a lot of community produced documentation, but since it is open source there is no vendor support. Businesses looking for support from a vendor may prefer proprietary database solutions.

Microsoft SQL Server supports Windows and Linux, but doesn’t have support for other operating systems.  Businesses running servers on OS X and Unix will need to consider other options.  Additionally, While Microsoft SQL Server offers vendor support, it isn’t as customizable as PostgreSQL.  If your organization has niche feature needs and a skilled development team, they can benefit from open source software like PostgreSQL.

Pricing

PostgreSQL is open source, so its source code is available free of charge.  Many third party organizations offer support and hosting for PostgreSQL with pricing dependent on the vendor.

Microsoft SQL Server pricing is dependent on the number of cores and users.  A free version exists for small amounts of data, but business licenses start at $931.00.

PostgreSQL, unlike other databases, is user-friendly and uses an open-source database. Ideal for relational databases, they can be accessed when speed and efficiency are required. It enables high-availability and disaster recovery replication from instance to instance. PostgreSQL can store data in a JSON format, including hashes, keys, and values. Multi-platform compatibility is also a big selling point. We could, however, use all the DBMS’s cores. While it works well in fast environments, it can be problematic in slower ones or cause multiple master replication.

Microsoft SQL Server is a great RDBMS and meets all of our requirements. If you need a stable DB platform to support your line of a business application you'll be well served. Licensing costs are far cheaper, more portable and a lot more user friendly than Oracle. Product support and security patches from Microsoft are strong.

Pros
PostgreSQL Global Development Group
  • The stability it offers, its speed of response and its resource management is excellent even in complex database environments and with low-resource machines.
  • The large amount of resources it has in addition to the many own and third-party tools that are compatible that make productivity greatly increase.
  • The adaptability in various environments, whether distributed or not, [is a] complete set of configuration options which allows to greatly customize the work configuration according to the needs that are required.
  • The excellent handling of referential and transactional integrity, its internal security scheme, the ease with which we can create backups are some of the strengths that can be mentioned.

  • Easy integration with MSBI to perform data analysis
  • Data Security
  • Easy to understand and use
  • Very easy to export database and tables in the form of SQL query or a script

Cons
PostgreSQL Global Development Group
  • The query syntax for JSON fields is unwieldy when you start getting into complex queries with many joins.
  • I wish there was a distinction (a flag) you could set for automated scripts vs working in the psql CLI, which would provide an 'Are you sure you want to do X?' type prompt if your query is likely to affect more than a certain number of rows. Especially on updates/deletes. Setting the flag in the headless(scripted) flow would disable the prompt.
  • Better documentation around JSON and Array aggregation, with more examples of how the data is transformed.

Microsoft
  • The import/export process can be tricky to follow with lots of steps and could be better for importing flat files
  • Obtaining help from Microsoft is cumbersome and often other internet sources are better and quicker
  • The documentation is not great and again it's generally better to obtain help elsewhere if needed

Usability
PostgreSQL Global Development Group
Postgresql is the best tool out there for relational data so I have to give it a high rating when it comes to analytics, data availability and consistency, so on and so forth. SQL is also a relatively consistent language so when it comes to building new tables and loading data in from the OLTP database, there are enough tools where we can perform ETL on a scalable basis.

SQL Server mostly 'just works' or generates error messages to help you sort out the trouble. You can usually count on the product to get the job done and keep an eye on your potential mistakes. Interaction with other Microsoft products makes operating as a Windows user pretty straight forward. Digging through the multitude of dialogs and wizards can be a pain, but the answer is usually there somewhere.

There are several companies that you can contract for technical support, like EnterpriseDB or Percona, both first level in expertise and commitment to the software.
But we do not have contracts with them, we have done all the way from googling to forums, and never have a problem that we cannot resolve or pass around. And for dozens of projects and more than 15 years now.

We managed to handle most of our problems by looking into Microsoft's official documentation that has everything explained and almost every function has an example that illustrates in detail how a particular functionality works. Just like PowerShell has the ability to show you an example of how some cmdlet works, that is the case also here, and in my opinion, it is a very good practice and I like it.

Other than SQL taking quite a bit of time to actually install there are no problems with installation. Even on hardware that has good performance SQL can still take close to an hour to install a typical server with management and reporting services.

Postgres stacks up just [fine] along the other big players in the RDBMS world. It's very popular for a reason. It's very close to MySQL in terms of cost and features - I'd pick either solution and be just as happy. Compared to Oracle it is a MUCH cheaper solution that is just as usable.

Return on Investment
PostgreSQL Global Development Group
  • The user-role system has saved us tons of time and thus money. As I mentioned in the "Use Case" section, Postgres is not only used by engineering but also finance to measure how much to charge customers and customer support to debug customer issues. Sure, it's not easy for non-technical employees to psql in and view raw tables, but it has saved engineering hundreds of man-hours that would have had to be spent on building equivalent tools to serve finance or customer support.
  • It provides incredibly trustworthy storage for wherever customer data dumped in. In our 6 years of Postgres existence, we have not lost a byte of customer data due to Postgres messing up a transaction or during the multiple times the hard-drives failed (thanks to ACID compliance!).
  • This is less significant, but Postgres is also quite easy to manage (unless you are going above and beyond to squeeze out every last bit of performance). There's not much to configure, and the out of the box settings are quite sane. That has saved us engineers lots of time that would have gone into Postgres administration.

  • Increased accuracy - We went from multiple users having different versions of an Excel spreadsheet to a single source of truth for our reporting.
  • Increased Efficiency - We can now generate reports at any time from a single source rather than multiple users spending their time collating data and generating reports.
  • Improved Security - Enterprise level security on a dedicated server rather than financial files on multiple laptop hard drives.
