The SQL is 90 percent the same. The differences show up as you grow.
Direct answer
MySQL and PostgreSQL are both mature, open-source relational databases. PostgreSQL is known for advanced features and strict standards support. MySQL is popular, widely hosted and easy to begin with. For learning, either is fine because core SQL skills transfer.
Comparison

|---|---|---|
| Known for | simplicity, wide hosting | advanced features, extensibility |
