We have many indexes on a table. The chance is that any column could be some part of an index. I understand that when an index has a column that is updated, we can't use HOT, because the index entry could point to a totally different row. But if I have 10 indexes, if only 1 index will be updated, why the rest 9 indexes couldn't use HOT update?
