What To Know About Postgres if You’re Coming From SQL Server

Peeking into the differences between SQL Server and Postgres reveals a landscape where both databases, though rooted in SQL, have distinct dialects and community dynamics. SQL Server, developed by Microsoft, uses T-SQL and is characterized by a structured development process with features rolled out according to a corporate roadmap, while Postgres, an open-source platform, thrives on community contributions and modularity, exemplified by its use of PL/pgSQL. Key differences include Postgres's reliance on double quotes for identifiers, its use of the LIMIT clause instead of SQL Server's TOP, and the distinct approaches to string concatenation and date functions. The community-driven nature of Postgres allows for faster adoption of new features and flexibility in tooling and hosting, contrasting with SQL Server's integrated ecosystem and vendor-specific optimizations. For those accustomed to SQL Server's ecosystem, transitioning to Postgres involves embracing a more global community and adapting to its unique features and operational models, while still benefiting from shared SQL fundamentals.
