pub trait MutationRowCatalog: Sync {
    // Required methods
    fn column_definitions(
        &self,
        table: &str,
    ) -> Result<Option<Vec<ColumnDef>>, String>;
    fn column_names(&self, table: &str) -> Result<Vec<String>, String>;
    fn view_schema(&self, name: &str) -> Result<RowSchema, SQLError>;
}
