- Compatibility: Nearly 100% compatible, minimal migration effort
- Process: Direct dump and restore typically sufficient
- Testing: Verify stored procedures and specific MySQL functions
- Compatibility: Moderate differences in SQL syntax and functions
- Process: May require application code changes
- Tools: Use MySQL-to-PostgreSQL migration tools or custom scripts
- Testing: Thorough testing of complex queries and stored procedures
- Always benchmark with your specific workload
- Consider read-heavy vs write-heavy patterns
- Test with production-scale data sets
- Evaluate concurrent connection handling
-
Start with MySQL if:

-
Choose MariaDB if:
- You want MySQL compatibility with open governance
- You need additional storage engines or features
- You’re concerned about Oracle’s control of MySQL
- You want better licensing terms
-
Choose PostgreSQL if:
- You need advanced SQL features
- Data integrity is paramount
- You’re building complex analytical applications
- You need extensive extensibility
-
Choose SQLite if:
- You’re building embedded applications
- You need zero-configuration setup
