1. Overview

2. Key Differences

A. Data Types and Extensibility

• PostgreSQL supports advanced data types like JSONB, XML, arrays, and custom types.
• MySQL offers limited JSON support and lacks extensibility for custom data types.

B. Performance

• PostgreSQL is optimized for complex queries and analytics, excelling in multi-join operations.
• MySQL is tailored for read-heavy workloads, performing well in simple queries.

C. Replication and Clustering

3. Use Cases

4. Pros and Cons

PostgreSQL

Pros:

• Advanced indexing and full-text search.
• Extensible with procedural languages like PL/pgSQL.
• Robust handling of large datasets.

Cons:

• Steeper learning curve for new users.
• Slower in simple read-heavy queries.

MySQL

Pros:

• Simple to set up and use.
• High performance in read-heavy applications.
• Wide hosting support, including shared hosting.

Cons:

• Limited advanced features compared to PostgreSQL.
• Lacks complete ACID compliance in certain engines (e.g., MyISAM).

5. Which One Should you Choose?

Example Scenario
