MySQL vs PostgreSQL: Which is best for you?

Biggest benefit that I see with MySQL is it supports addition of columns to desired position (using BEFORE and AFTER keyword), this basic functionality is not provided with premier tools like Postgre SQL.

Compared to other databases like PostgreSQL or Oracle, MySQL lacks some advanced features such as full-text search and partial indexes, which may be a limitation for certain use cases.

Security is very important in IoT. PostgreSQL offers robust security features such as SSL encryption and row-level access controls, ensuring that data is kept safe and secure.

One of the drawback of the PostgreSQL is CPU usage is rather high.
