PostgreSQL VS H2 Database Engine
H2 Database Engine is a lightweight, in-memory database ideal for development and testing, while PostgreSQL is a powerful, fully-featured relational database suited for production applications and large datasets. PostgreSQL offers better scalability, advanced features, and a strong community, making it more suitable for enterprise-level applications.
