Comparison
PostgreSQL vs MySQL
Overview
PostgreSQL is a powerful, open-source object-relational database with 35+ years of active development. It is known for reliability, standards compliance, extensibility (JSON, full-text search, pgvector) and strong ACID guarantees, making it a default choice for everything from small apps to large-scale analytics.
MySQL is a widely deployed open-source relational database owned by Oracle. It powers a huge share of web applications thanks to its speed, maturity, replication options and broad ecosystem support across every major framework and hosting provider.
