Enum postgres_parser::sys::DefElemAction

#[repr(u32)]pub enum DefElemAction {
    DEFELEM_UNSPEC,
    DEFELEM_SET,
    DEFELEM_ADD,
    DEFELEM_DROP,
}

DefElem a generic "name = value" option definition

In some contexts the name can be qualified. Also, certain SQL commands allow a SET/ADD/DROP action to be attached to option settings, so it's convenient to carry a field for that too. (Note: currently, it is our practice that the grammar allows namespace and action only in statements where they are relevant; C code can just ignore those fields in other statements.)
