Should I learn PostgreSQL or SQL Server?
For students who have little to no experience with SQL and are looking to gain the most broadly applicable skills, I recommend starting with PostgreSQL. Despite the overwhelming popularity of MySQL, PostgreSQL may be a better choice because its syntax most closely conforms to Standard SQL.
Why use SQL Server over Postgres?
PostgreSQL has a better concurrency management system. It handles very well the case where multiple processes can access and modify shared data at the same time. On the other hand, SQL Server has underdeveloped concurrency and you can easily get various locked, blocked, and deadlocked reports in the log.
Should I choose MySQL or PostgreSQL?
