Change main.rs to this: ```rust use anyhow::Result; use opendal::services::Postgresql; use opendal::Operator; #[tokio::main] async fn main() -> Result<()> { let mut builder = Postgresql::default() .root("/") .connection_string("postgresql://you_username:[email protected]:5432/your_database") .table("your_table") // key field type in the table should be compatible with Rust's &str like text .key_field("key") // value field type in the table should be compatible with Rust's Vec<u8> like bytea .value_field("value"); let op = Operator::new(builder)?.finish(); Ok(()) } ``` 4.
