Usage

use duroxide_pg::PostgresProvider;
use duroxide::Worker;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Create a provider with the database URL
    let provider = PostgresProvider::new("postgres://user:password@localhost:5432/mydb").await?;

    // Use with a Duroxide worker
    let worker = Worker::new(provider);
    // ... register orchestrations and activities, then run
    
    Ok(())
}

let provider = PostgresProvider::new_with_schema(
    "postgres://user:password@localhost:5432/mydb",
