Invalid SQL Statement in rust integrration test

[tobyhede]

The rust integration test uses invalid SQL and does not actually work.

The test_prepared_statements function in the Rust integration tests uses this code & statement:

    match sqlx::query("SELECT one").fetch_all(&pool).await {
        Ok(_) => (),
        Err(err) => {
            if err.to_string().contains("prepared statement") {
                panic!("prepared statement error: {}", err);
            }
        }
    }

SELECT one is not valid SQL and produces an error

Severity: ERROR Code: 42703 Message: column "one" does not exist Position: 8 File: parse_relation.c Line: 3666 Routine: errorMissingColumn

The test "passes" because the error handling ignores the errors

To Reproduce

1. Run the integration tests
2. pgcat output will contain the above error message

Expected behavior

The rust test should run without errors in either the test or the running proxy.
