{"slug":"mysql-vs-postgresql","title":"MySQL vs PostgreSQL","url":"https://www.aversusb.net/compare/mysql-vs-postgresql","faqCount":5,"faqs":[{"question":"Which is faster: MySQL or PostgreSQL?","answer":"For simple read queries, MySQL is 15-20% faster with lower latency (~45ms vs ~52ms for 1M row scans). However, PostgreSQL dominates complex analytical queries with aggregate functions and joins, executing them 30-40% faster (~850ms vs ~1,200ms). Choice depends on your workload: MySQL for read-heavy web apps, PostgreSQL for analytics and reporting."},{"question":"Can I use JSON with both databases?","answer":"Both support JSON, but PostgreSQL's implementation is far superior. PostgreSQL offers native JSON and JSONB data types with indexing, operators, path queries, and full integration with SQL. MySQL's JSON support (added in 5.7) is basic—primarily for storage and basic operations. If JSON is core to your application, PostgreSQL is the clear winner."},{"question":"Which requires less maintenance and resources?","answer":"MySQL requires significantly fewer resources: 50MB minimum memory vs PostgreSQL's 100MB, and smaller default connection pools. MySQL is easier to set up and configure with simpler administration. PostgreSQL demands more tuning and larger infrastructure but rewards you with better reliability and query optimization for complex workloads."},{"question":"Is one more reliable or secure than the other?","answer":"Both are reliable and secure when properly configured. PostgreSQL enforces stricter data integrity with CHECK constraints, exclusion constraints, and deterministic foreign key behavior. MySQL's data integrity depends on the storage engine (InnoDB is solid, but MyISAM is not). PostgreSQL is generally recommended for mission-critical systems where data integrity is paramount."},{"question":"Which scales better for large applications?","answer":"MySQL scales horizontally better for read-heavy workloads through simple master-slave replication. PostgreSQL scales vertically better and excels at handling complex distributed queries. For massive datasets with complex analytics, PostgreSQL wins. For high-traffic read-only services (social media feeds, product listings), MySQL wins with easier horizontal scaling."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/mysql-vs-postgresql#faq","url":"https://www.aversusb.net/compare/mysql-vs-postgresql","inLanguage":"en-US","name":"MySQL vs PostgreSQL — FAQ","description":"Frequently asked questions about MySQL vs PostgreSQL","dateModified":"2026-07-05T18:01:48.979Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/mysql-vs-postgresql#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Which is faster: MySQL or PostgreSQL?","acceptedAnswer":{"@type":"Answer","text":"For simple read queries, MySQL is 15-20% faster with lower latency (~45ms vs ~52ms for 1M row scans).
