Transaction functions for PostgreSQL

These functions provide a way to execute queries within a transaction. The transaction is automatically committed when the function returns successfully, or rolled back if an error occurs.

Example:

use sal_postgresclient::{transaction, QueryParams};

let result = transaction(|client| {
    // Execute queries within the transaction
    client.execute("INSERT INTO users (name) VALUES ($1)", &[&"John"])?;
    client.execute("UPDATE users SET active = true WHERE name = $1", &[&"John"])?;

    // Return a result from the transaction
    Ok(())
});
