PostgreSQL vs MariaDB: Frequently Asked Questions

Which is faster: PostgreSQL or MariaDB?

Performance depends on the workload. MariaDB typically performs better for simple read operations and basic queries, while PostgreSQL excels in complex queries, analytical workloads, and concurrent operations. Both can achieve excellent performance with proper optimization.

Can I easily migrate from MySQL to MariaDB vs PostgreSQL?

MariaDB is designed as a drop-in replacement for MySQL, making migration very straightforward. PostgreSQL migration from MySQL requires more effort due to syntax differences, data type mappings, and feature variations, but offers more advanced capabilities.

Which database has better JSON support?

PostgreSQL has significantly better JSON support with its native JSONB data type, indexing capabilities, and rich operators. MariaDB has basic JSON support but lacks the advanced features and performance optimizations of PostgreSQL's JSONB.

Is MariaDB really free compared to PostgreSQL?

Both PostgreSQL and MariaDB are completely free and open source. MariaDB offers additional enterprise features through MariaDB Enterprise, while PostgreSQL relies on third-party vendors for enterprise support and features.

Which database is better for web applications?

Both are excellent for web applications. MariaDB is popular for simple web apps and CMSs due to its MySQL compatibility and ease of use. PostgreSQL is better for complex web applications requiring advanced features, data integrity, and analytical capabilities.
