MySQL vs PostgreSQL.
MySQL and PostgreSQL are the two dominant open-source relational databases. Both are excellent. Choice usually comes down to specific feature needs.
(01) — Strengths
What each does best.
MySQL
- Widest managed hosting support — every shared host runs MySQL
- Simpler operational model
- Slightly faster for simple read-heavy workloads
- Excellent WordPress + PHP fit
PostgreSQL
- Richest feature set — JSON, arrays, full-text search, geospatial
- Better ACID compliance
- Superior for analytical queries
- Better concurrency handling at scale
(02) — Head-to-head
Direct comparison.
| Criterion | MySQL | PostgreSQL |
|---|---|---|
| Hosting availability | Everywhere | Most managed platforms |
| Feature depth | Solid | Extensive |
| JSON handling | Basic | First-class |
| Read performance (simple queries) | Slightly faster | Excellent |
| Complex query performance | Good | Better |
| Enterprise features | Solid | Excellent |
(03) — Decision
When to pick each.
Pick MySQL when
Shared hosting deployments, WordPress-adjacent projects, simple read-heavy web apps.
Pick PostgreSQL when
Anything with complex data model, JSON-heavy workloads, analytical queries, or high-concurrency writes.
(04) — FAQ
Common questions.
Excellent for embedded or single-user scenarios. Not for concurrent web workloads.
PostgreSQL with JSONB usually wins. You get relational + document in one system.
