I think we should "just" split this into different flag values for
insert/update/delete.
I.e. something like
/* flags for heap insert and multi insert */
#define XLH_INSERT_ALL_VISIBLE_CLEARED
#define XLH_INSERT_LAST_MULTI_INSERT
#define XLH_INSERT_IS_SPECULATIVE
#define XLH_INSERT_CONTAINS_NEW_TUPLE
/* flags for update */
#define XLH_UPDATE_OLD_ALL_VISIBLE_CLEARED
#define XLH_UPDATE_NEW_ALL_VISIBLE_CLEARED
#define XLH_UPDATE_CONTAINS_OLD_TUPLE
#define XLH_UPDATE_CONTAINS_OLD_KEY
#define XLH_UPDATE_CONTAINS_NEW_TUPLE
#define XLH_UPDATE_PREFIX_FROM_OLD
#define XLH_UPDATE_SUFFIX_FROM_OLD
/* flags for delete */
#define XLH_DELETE_ALL_VISIBLE_CLEARED
#define XLH_DELETE_CONTAINS_OLD_TUPLE
#define XLH_DELETE_CONTAINS_OLD_KEY
Greetings,
