MySQL vs PostgreSQL: Which Database Should You Learn?

MySQL and PostgreSQL are the two giants of open-source databases. Both are excellent; they differ in philosophy — MySQL prizes simplicity and speed, PostgreSQL prizes standards and extensibility.

Key Points

• MySQL: easier setup, massive hosting support, great read performance
• PostgreSQL: richer SQL features, stricter standards compliance, extensible types
• Both now support window functions, CTEs and JSON well
• PostgreSQL's advanced analytics functions give it an edge for complex analysis
• MySQL dominates web hosting; PostgreSQL is popular in data engineering
• Career answer: concepts transfer — learn one deeply, the other follows quickly
