Function create_pool 

pub fn create_pool(database_url: &str) -> OrmResult<Pool>

Create a connection pool from a database URL.

This is a convenience helper that uses NoTls and small default settings (suitable for local/dev). For production, prefer:

• create_pool_with_tls if your DB requires TLS
• create_pool_with_manager_config to inject pool/manager tuning

Example

let pool = pgorm::create_pool("postgres://user:pass@localhost/db")?;
let client = pool.get().await?;
