Struct Pushdown 

pub struct Pushdown {
    pub sql: String,
    pub order_table: Option<String>,
}

A pushdown plan: SQL whose execution is provably identical to the Quarb query’s — plus the table whose primary key must order the rows (None for a single aggregate row, where order is moot). The driver appends the ORDER BY, since the key lives in its catalog.

sql: String
