Choose MySQL if you're building a simple web application, prioritize hosting availability, need maximum read speed, or are migrating existing MySQL code. PostgreSQL's feature gap advantage now outweighs MySQL's historical speed advantage for most new projects."},{"question":"Which database is faster—MySQL or PostgreSQL?","answer":"MySQL is 15-20% faster on simple SELECT queries due to optimized read paths. However, PostgreSQL is 60-65% faster on complex analytical queries with JOINs, aggregations, and window functions. For read-heavy workloads with simple schemas, MySQL wins; for data warehousing and analytics, PostgreSQL dominates."},{"question":"Is MySQL ACID-compliant by default?","answer":"No. MySQL's default storage engine (as of 5.7+) is InnoDB, which is ACID-compliant, but the older MyISAM engine is not. PostgreSQL guarantees ACID compliance on all transactions by default without requiring engine selection, making it safer for critical financial and banking applications."}],"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 offers superior advanced features like JSON support, full-text search, and window functions, while MySQL excels in simplicity, speed for read-heavy workloads, and widespread hosting support","dateModified":"2026-07-08T03:34:30.073Z"},"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 offers superior advanced features like JSON support, full-text search, and window functions, while MySQL excels in simplicity, speed for read-heavy workloads, and widespread hosting support.
