Struct CopyRelation 

pub struct CopyRelation {
    pub name: String,
    pub columns: Vec<String>,
    pub selected: Vec<usize>,
    pub query: Node,
    pub partitions: Option<Vec<u32>>,
}

The relation of a COPY ... TO and the query that reads its rows.

Fields

name: String

The name of the relation, for the errors.

columns: Vec<String>

The names of the user columns of the relation, in the order of the catalog.

selected: Vec<usize>

The columns that COPY sends, as indexes into columns.

query: Node

SELECT of the selected columns FROM ONLY the relation. For a partitioned table, the query reads the partitions, and tableoid comes after the selected columns.

partitions: Option<Vec<u32>>

The partitions of a partitioned table that have rows, in the order of find_all_inheritors. DoCopyTo sends the rows of each partition in this order.
