Learn PostgreSQL by leveraging your SQL Server expertise
Traditional PostgreSQL tutorials assume you're starting from scratch. But you're not—you're an experienced SQL Server DBA with years of database knowledge. This guide respects your expertise and maps your existing knowledge to PostgreSQL equivalents.
Instead of learning PostgreSQL "from the beginning," you'll discover how the concepts you already know translate to PostgreSQL's world. It's not about learning databases again; it's about learning a different database dialect.
Leverage, Don't Replace: Your SQL Server knowledge is valuable. We build on it rather than replacing it.
Compare, Don't Memorize: Side-by-side comparisons help you understand differences in context.
Practice, Don't Just Read: Every example is copy-pasteable and ready to run.
Understand Why: We explain not just what's different, but why PostgreSQL chose different approaches.
Find concepts, commands, or topics instantly with intelligent search that understands both SQL Server and PostgreSQL terminology.
Click any language label to copy code snippets directly to your clipboard. No more manual selection or typos.
Fully responsive design that works perfectly on desktop, tablet, and mobile devices.
Zero dependencies and optimized performance mean sub-second loading times and smooth interactions.
This guide covers the essential DBA tasks you perform daily:
This guide is built with vanilla HTML, CSS, and JavaScript—no frameworks or build tools required. It's designed to be fast, accessible, and maintainable. The entire application loads in under 2 seconds and works offline once cached.
The code is open source and available on GitHub. Contributions are welcome from the DBA community to help make this resource even better.
This guide contains a mix of community-contributed content and AI-assisted content. For AI-generated topics, every code example is executed and validated against real SQL Server and PostgreSQL instances before publishing — so the code you copy and paste has actually been run.
That said, mistakes are possible. AI can misunderstand edge cases, produce subtly incorrect examples, or miss important caveats that an experienced DBA would catch. We're open about this because we think transparency builds more trust than pretending everything is perfect.
If you find an error, an oversimplification, or a better way to explain something, we genuinely want to hear from you. You can open an issue on GitHub or submit your own curated content via a pull request. Community corrections and contributions are what keep this guide trustworthy over time.
Ready to begin your PostgreSQL journey? Head back to the main guide and start with a topic you're familiar with in SQL Server. You'll be surprised how quickly the pieces fall into place.
Remember: You're not learning databases from scratch. You're learning a new way to do things you already know how to do.
