Struct postgres_parser::sys::A_Indirection

#[repr(C)]pub struct A_Indirection {
    pub type_: NodeTag,
    pub arg: *mut Node,
    pub indirection: *mut List,
}

A_Indirection select a field and/or array element from an expression

The indirection list can contain A_Indices nodes (representing subscripting), string Value nodes (representing field selection the string value is the name of the field to select), and A_Star nodes (representing selection of all fields of a composite type). For example, a complex selection operation like (foo).field1[42][7].field2 would be represented with a single A_Indirection node having a 4element indirection list.

Currently, A_Star must appear only as the last list element the grammar is responsible for enforcing this!
