abstract: 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. PostgreSQL is ACID-compliant by default; MySQL requires InnoDB engine configuration.
text: ACID Compliance. JSON Data Type Support. Window Functions. Common Table Expressions (CTEs). Full-Text Search Capabilities. Read Query Performance (simple). Hosting Availability
conclusion text: Choose PostgreSQL if you need advanced analytics, complex queries, strict data integrity, or JSON handling—it's the better choice for enterprise applications and data warehouses. Choose MySQL if you prioritize simplicity, require maximum hosting compatibility, or are building read-heavy web applications with straightforward schemas where its 15-20% speed advantage matters.

main entity: Which should I choose for a new project in 2026?
  type: Question
  accepted answer: Answer
    text: Choose PostgreSQL if your project involves analytics, complex queries, JSON handling, or strict data integrity needs. 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.
    language: en-US
main entity: Which database is faster—MySQL or PostgreSQL?
  type: Question
  accepted answer: Answer
    text: 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.
    language: en-US
main entity: Is MySQL ACID-compliant by default?
  type: Question
  accepted answer: Answer
    text: 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.
    language: en-US
main entity: Can I use JSON with both databases?
  type: Question
  accepted answer: Answer
    text: Both support JSON, but PostgreSQL's JSONB (binary JSON) is vastly superior. JSONB allows indexing, query operators (->), and sub-millisecond performance on large documents. MySQL's JSON support is basic—storing JSON as text without native indexing capability, resulting in slower queries on large datasets.
    language: en-US
main entity: Why does MySQL appear on more hosting providers?
  type: Question
  accepted answer: Answer
    text: MySQL has been the default database for web hosting since the 1990s due to its simplicity and lower resource requirements. PostgreSQL requires more configuration expertise and memory (2-3x more baseline RAM). Many legacy shared hosting providers still don't support PostgreSQL, though adoption is growing (currently 85% of providers offer it).
