PostgreSQL vs MySQL in 2026: a pragmatic take
Both are excellent. The interesting question isn't which is better — it's which failure modes you can't recover from, and which hire will maintain your choice in five years.

I've run both in production for years: MySQL on logistics fleets taking 5,000 writes a second, Postgres on a multi-tenant SaaS with 40 custom fields per tenant. My honest position: both are right 95% of the time.
The decision usually resolves to three questions. What shape is your data — relational with JSON islands, or relational with heavy array/geometric types? Who maintains it in five years — your senior engineer, or the next hire you find on LinkedIn? And what will you regret — replication pain, or schema rigidity?
- Postgres when: multi-tenant SaaS, JSONB flexibility, full-text search, one-database-answers-everything pragmatism.
- MySQL when: classic transactional workloads, a strong ops culture already in place, or the team knows it cold.
The real risk in both cases isn't the engine — it's migrating away later. Keep your domain logic out of stored procedures, your IDs portable, and your migrations reversible. The database should be the least exciting decision on your architecture diagram.
