Comparisons & Buyer's Guides
MySQL vs MariaDB vs PostgreSQL
MySQL, its MariaDB fork, and PostgreSQL cover nearly all web hosting database needs — with different strengths. MariaDB tracks MySQL compatibility while adding engines and features; PostgreSQL brings stricter correctness, richer types, and analytical power at the cost of a smaller shared-hosting ecosystem. For WordPress and typical CMS estates the practical race is MySQL versus MariaDB, decided by version, tooling, and support.
Key points
- Default to what your applications support best — CMS compatibility decides more than benchmarks.
- Compare version-for-version, not brand-to-brand; MySQL 8 vs MariaDB 10.11 vs Postgres 15+ is the real contest.
- Weigh ecosystem: backup tooling, panel integration, and hireable DBAs favor MySQL/MariaDB in hosting.
- Choose PostgreSQL for complex queries, strict integrity, and JSON-heavy workloads done right.
- Test replication, backup, and restore workflows — operational fit beats feature lists.
- Mind licensing and support channels for commercial deployments.
- Benchmark with your queries, not sysbench defaults — workload shape decides winners.
- Plan major-version upgrades separately from engine switches; never both at once.
Field note
Choose by application compatibility first and benchmarks a distant second. The fastest database your CMS doesn't fully support is just a science project with uptime requirements.
Frequently asked questions
MariaDB or MySQL for WordPress?
Either serves excellently; pick by version freshness, tooling, and who supports your stack.
When does PostgreSQL win?
Complex relational logic, strict correctness needs, advanced types, and analytics-adjacent workloads.
Can we switch engines later?
Yes with migration tooling and testing — SQL dialects differ in the details that matter at scale.
What about managed database services?
Excellent for offloading ops where latency budgets allow; keep sovereignty and cost math honest.
