PostgreSQL and MySQL are top open-source databases. Both power web apps and enterprise systems, but differ in features, performance, and use cases.
PostgreSQL is object-relational, supporting complex data structures and custom types. MySQL is a purely relational system, focusing on simplicity and speed.
PostgreSQL supports more advanced data types like arrays, JSONB, and custom types. MySQL offers standard types and basic JSON support
PostgreSQL provides advanced indexing (B-tree, GiST, GIN) for complex queries. MySQL uses B-tree and hash indexes, excelling in simple, read-heavy workloads.
PostgreSQL closely follows SQL standards and offers features like materialized views and multi-language procedures. MySQL is easier to learn but less feature-rich.
MySQL is widely used for web apps and quick deployments. PostgreSQL is preferred for analytics, custom data, and applications needing advanced querying.
Pick PostgreSQL for complex, data-driven apps needing extensibility. Choose MySQL for fast, simple web projects or when ease of use is key.
