index maybe not used on maintenance #131

MengqiWu commented 3 years ago

in apply_delta() maybe just use all attributes not consider the index created when create ivm /*

For views without aggregates, all attributes are used as keys to identify a
tuple in a view. */ if (!query->hasAggs) keys = lappend(keys, attr);

Thank you for your feedback! That's good point. Actually, the index is used even when all attributes are used as a key, but we don't have to use some attributes if we have a unique key. I'll consider to fix this.
