You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: postgres.rs
    path of file: ./repos/dozer/dozer-ingestion/tests/test_suite/connectors
    
    the code of the file until where you have to start completion: use dozer_ingestion_connector::{async_trait, dozer_types::types::Field};
use dozer_ingestion_postgres::{
    connection::{client::Client, helper::connect},
    connector::{PostgresCo
    
    async fn start_cud(&self, operations: Vec<Operation>) {
        let mut client = connect(self.config.clone()).await.unwrap();
        let schema_name = self.schema_name.clone();
        let table_name = self.table_name.clone();
        let schema = self.schema.clone();
        tokio::spawn(async move {
            for operation in operations {
                client
                    .batch_execute(&operation_to_sql(
                        schema_name.as_deref(),
                        &table_name,
                        &operation,
                        &schema,
                    ))
                    .await
                    .unwrap();
            }
        });
    }
