Struct postgres_parser::nodes::ColumnRef

pub struct ColumnRef {
    pub fields: Option<Vec<Node>>,
    pub location: i32,
}

ColumnRef specifies a reference to a column, or possibly a whole tuple

The "fields" list must be nonempty. It can contain string Value nodes (representing names) and A_Star nodes (representing occurrence of a '*'). Currently, A_Star must appear only as the last list element the grammar is responsible for enforcing this!

Note: any container subscripting or selection of fields from composite columns is represented by an A_Indirection node above the ColumnRef. However, for simplicity in the normal case, initial field selection from a table name is represented within ColumnRef and not by adding A_Indirection.
