เลือก PostgreSQL for new applications in 2026 — it has superior JSONB support, ขั้นสูง indexing, richer SQL standards, and an incredible extension ecosystem (PostGIS, pgvector, TimescaleDB). เลือก MySQLif you're running WordPress, have existing MySQL infrastructure, or need the widest shared hosting support. PostgreSQL ชนะ 5-2 overall. Both are free and excellent — but PostgreSQL is the modern default.

Verified Data (April 2026)

MySQL: ฟรี + open source · Oracle-owned · Most popular DB worldwide · G2: 4.3/5

PostgreSQL: ฟรี + open source · Community-driven · Most ขั้นสูง open-source RDBMS · G2: 4.5/5

Both are 100% free and open-source. MySQL is owned by Oracle; PostgreSQL is community-driven. PostgreSQL รองรับ more ขั้นสูง ฟีเจอร์ (CTEs, window functions, JSONB, full-text search). MySQL is easier to set up and has broader hosting support. PostgreSQL has a higher G2 rating (4.5 vs 4.3).

ฟีเจอร์ ภาพรวม

PostgreSQL has become the default database for modern web development. Its JSONB support means you get NoSQL-like flexibility within a relational database. Window functions, CTEs, and ขั้นสูง indexing (GIN, GiST, BRIN) handle ซับซ้อน วิเคราะห์ข้อมูล natively. The extension ecosystem is unmatched — PostGIS for geospatial, pgvector for AI embeddings, TimescaleDB for time-series. It's the default for Supabase, Neon, Railway, and Render.

Managed Hosting (April 2026)

Provider	ฟรี Tier	Paid From
Supabase	500MB, 2 projects	$25/เดือน
Neon	0.5GB, scale-to-zero	$19/เดือน
AWS RDS	750 hrs/เดือน (12 months)	~$15/เดือน

Best for WordPress & Legacy Apps

MySQL

4.5/5

ฟรี (open source)

Massive ecosystem — WordPress, Drupal, every CMS
Simpler replication and easy to learn
Fastest for simple read-heavy queries

Weaker JSON support than PostgreSQL JSONB
Limited extension ecosystem
Oracle ownership creates licensing concerns

ฟีเจอร์ ภาพรวม

MySQL powers approximately 40% of all websites through WordPress alone. Its simplicity, massive community, and ubiquitous hosting support make it the path of least resistance for traditional web development. MySQL 8.0+ added window functions and CTEs, closing the gap with PostgreSQL. For read-heavy workloads with simple queries, MySQL's lower overhead can offer a performance edge. PlanetScale and AWS RDS make scaling MySQL straightforward.

AWS RDS MySQL	750 hrs/เดือน (12 months)	~$15/เดือน
DigitalOcean	No	$15/เดือน

ใครควรเลือกอะไร?

→ เลือก PostgreSQL if:

You're building a new SaaS application, need ขั้นสูง JSON storage (JSONB), geospatial data (PostGIS), vector search for AI (pgvector), or ซับซ้อน analytics. PostgreSQL is the default for Supabase, Neon, Railway, and most modern cloud platforms.

→ เลือก MySQL if:

You're running WordPress, Drupal, or another CMS that defaults to MySQL, have existing MySQL infrastructure and expertise, or need the widest shared hosting support. MySQL's simplicity and massive community make it easy to find developers and hosting.

→ ควรหลีกเลี่ยงทั้งคู่ถ้า:

You need a document database (MongoDB), key-value store (Redis), or graph database (Neo4j). For serverless, look at Neon (PostgreSQL) or PlanetScale (MySQL) specifically.

Best For Different Needs

Overall Winner:PostgreSQL — Best all-around choice for most teams

Also ข้อเสียidered

We evaluated several other tools in this category before focusing on PostgreSQL vs MySQL. Here are the runners-up and why they didn't make our final comparison:

VS Code— The most popular code editor with vast extensions, but can become slow with many plugins.

JetBrains IDEs— top-tier language-specific features, but heavy on system resources and expensive.

Neovim— Ultimate keyboard-driven editor for power users, but steep learning curve.

ความเห็นบรรณาธิการ

I've used both in production for over a decade. Here's the short version: if you're starting fresh, PostgreSQL. If you're on WordPress, MySQL. Don't overthink it. The ทีม I've seen waste the most time are the ones debating this for weeks instead of building. Both databases will handle millions of rows just fine.
