{"slug":"mysql-vs-postgresql","question":"MySQL vs PostgreSQL","answer":"PostgreSQL is a more feature-rich relational database with advanced capabilities like JSON support, full-text search, and window functions, while MySQL prioritizes simplicity and raw speed for web applications.

Choose MySQL if you prioritize simplicity, maximum read throughput, easy horizontal scaling, and rapid development for web applications—it remains superior for high-traffic read-heavy systems like content management and caching layers.","keyDifferences":[{"label":"ACID Compliance","winner":"tie","entityAValue":"Full ACID with all storage engines (InnoDB default)","entityBValue":"Full ACID compliance by default"},{"label":"Advanced Data Types","winner":"a","entityAValue":"JSON, Arrays, Ranges, UUID, Geometric types","entityBValue":"Basic data types only (JSON added in 5.7)"},{"label":"Query Performance (Simple Reads)","winner":"b","entityAValue":"~15-20% faster on simple SELECT queries","entityBValue":"Slower on simple queries, optimized for complex ones"},{"label":"Full-Text Search","winner":"a","entityAValue":"Native full-text search with ranking and relevance","entityBValue":"Basic full-text search capability"},{"label":"Replication Complexity","winner":"a","entityAValue":"Statement-based, Row-based, or Mixed replication","entityBValue":"Logical and physical replication with streaming"}],"winner":{"slug":"mysql","name":"MySQL"},"confidence":"high","entities":[{"name":"MySQL","slug":"mysql","url":"https://www.aversusb.net/entity/mysql","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/mysql"},{"name":"PostgreSQL","slug":"postgresql","url":"https://www.aversusb.net/entity/postgresql","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/postgresql"}],"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."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/mysql-vs-postgresql","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/mysql-vs-postgresql), PostgreSQL is a more feature-rich relational database with advanced capabilities like JSON support, full-text search, and window functions, while MySQL prioritizes simplicity and raw speed for web app","dateModified":"2026-07-05T18:01:48.979Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/mysql-vs-postgresql","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/mysql-vs-postgresql","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/mysql-vs-postgresql","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/mysql-vs-postgresql#claimreview","url":"https://www.aversusb.net/compare/mysql-vs-postgresql","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"MySQL vs PostgreSQL","reviewBody":"PostgreSQL is a more feature-rich relational database with advanced capabilities like JSON support, full-text search, and window functions, while MySQL prioritizes simplicity and raw speed for web applications.
