PostgreSQL vs MySQL for web applications

How to choose between PostgreSQL and MySQL based on data, queries, operations and the team that will maintain the application. This guide explains the practical decisions behind it and what those decisions mean for the people using and operating the product.

Both are credible production databases

PostgreSQL and MySQL support substantial web applications. Performance and reliability depend more on schema design, indexing, queries and operations than on a simplistic product ranking.

Where PostgreSQL stands out

Advanced SQL, JSONB, extensions, geospatial tooling and expressive indexing can help products with richer query or data requirements. Those capabilities are valuable only when the application genuinely uses them.

Where MySQL makes sense

MySQL has broad hosting support, familiar tooling and an enormous knowledge base. It is often a pragmatic choice for conventional transactional applications and existing PHP estates.

Consider operations as well as development

Backups, replication, monitoring and staff experience shape total ownership cost. Choosing an unfamiliar database for one feature can add more risk than it removes.

Make the choice from evidence

Sketch the data model, identify difficult queries and prototype uncertain workloads. A documented decision is more useful than choosing whichever technology is currently fashionable.
