Method MaybeSetCustomOid

pkg/sql/sem/tree/datum.go:5022–5033

MaybeSetCustomOid checks whether t has a special oid that we want to set into d. Must be kept in sync with DArray.ResolvedType. Returns an error if t is not an array type.

(t *types.T)

// d. Must be kept in sync with DArray.ResolvedType. Returns an error if t is
// not an array type.
func (d *DArray) MaybeSetCustomOid(t *types.T) error {
	if t.Family() != types.ArrayFamily {
		return errors.AssertionFailedf("expected array type, got %s", t.SQLStringForError())
	}
	switch t.Oid() {
	case oid.T_int2vector:
		d.customOid = oid.T_int2vector
	case oid.T_oidvector:
		d.customOid = oid.T_oidvector
	}
	return nil
}

// ResolvedType implements the TypedExpr interface. Must be kept in sync with
// DArray.MaybeSetCustomOid.
