PostgreSQL vs MySQL | UpGuard

The document compares PostgreSQL and MySQL, outlining their architectures, feature sets (standards compliance, indexing options, MVCC, replication strategies, partitioning), security controls (roles/privileges, authentication methods, SSL, ACL/pg_hba), performance considerations, scalability, and typical use cases. It highlights PostgreSQL’s richer SQL standards support, extensibility, and concurrency strengths versus MySQL’s simplicity, widespread adoption, and ecosystem, and provides guidance on selection while briefly contrasting SQL systems with NoSQL alternatives.
