// DropBehavior captures whether a Postgres DROP statement was qualified with
// RESTRICT or CASCADE. The numeric values mirror pganalyze/pg_query_go's
// DropBehavior enum:
//
// DropBehavior_UNDEFINED = 0 (no behavior word supplied — same as RESTRICT in PG)
// DROP_RESTRICT = 1
// DROP_CASCADE = 2
type DropBehavior uint

const (
DropBehaviorUndefined DropBehavior = 0
DropBehaviorRestrict DropBehavior = 1
DropBehaviorCascade DropBehavior = 2
)

func (n *DropBehavior) Pos() int {
return 0
