Over the years, I have extensively worked on both SQL Server and PostgreSQL, garnering hands-on experience in data management using these powerful systems. As a user, I found PostgreSQL to be very user-friendly, thanks to the native PL/PostgreSQL. SQL Server, on the other hand, is robust and feature-packed, making it a go-to choice for many. Each has unique strengths, but certain features make PostgreSQL a standout in a few key areas.

1) PostgreSQL uses write-ahead log shipping, data partitioning, shared-disk failover, and many other methods to maintain high availability. Tools like EDB Postgres Failover Manager even automate failover during database failure. SQL Server also has similar high availability tools, but the automatic failover service comes exclusive to the enterprise edition.

2) PostgreSQL and SQL Server use unique programming languages - PostgreSQL utilizes PL/pgSQL while SQL Server uses T-SQL. However, PostgreSQL gains an edge with its added functionalities like user-defined types, JSON support and advanced triggers that enhance the overall user experience.

3) SQL Server's scalability is tied to its buffer pool. Unlike PostgreSQL, SQL Server handles everything in one pool, a design choice that can limit scalability but requires less management.

4) Both these systems offer robust support for Temporary tables. A handy tool for storing intermediate results and improving database organization, who will say no to temporary tables.

5) PostgreSQL's defragmentation process carries a heavy load on the CPU, unlike SQL Server. SQL server uses an efficient garbage collector that doesn't put a lot of weight on the system. It's a clear win for SQL Server in this aspect.

6) Both support indexes, with slight nuances in their approach. SQL Server provides an automated functionality for index management, while PostgreSQL supports index-based table organization.

7) Views can be described as virtual tables that do not store data in a physical manner. Typically, they are utilized for the purpose of security - their function is to restrict user access to data. Notably, updatable views are supported by both PostgreSQL and SQL Server.

8) PostgreSQL and Microsoft SQL Server are both databases, but they vary in their structure. PostgreSQL is an object-relational database, whereas Microsoft SQL Server embodies a relational database system. It implies that PostgreSQL avails more intricate data types and supports object inheritance, even though this makes it slightly more complex to work with.


PostgreSQL and SQL Server are both functional and powerful platforms. However, in my experience, SQL Server is better suited for businesses requiring extensive use of Microsoft products, while PostgreSQL's operating system compatibility makes it ideal for businesses seeking top-tier functionality
