> While I am normally of an opinion that our own connection pool should not compete with 3rd parties, and we should instead focus on ORM features of the framework, I ran into a few scenarios that made me reconsider and work on adding at least some features. 
> Specifically "validation query" that is run before a connection is given to the pool user is a must have. Otherwise the user gets timed out connections. So arguably the pool is broken as a result.
> While we are at it, we might rename connection pool classes, and provide a builder for the pool. PoolManager is not the most intuitive name for the pooling DataSource and its construction API is far from easy.
