Alvaro Herrera 2fd8685e7f Simplify check of modified attributes in heap_update ... The old coding was getting more complicated as new things were added, and it would be barely tolerable with upcoming WARM updates and other future features such as indirect indexes. The new coding incurs a small performance cost in synthetic benchmark cases, and is barely measurable in normal cases. A much larger benefit is expected from WARM, which could actually bolt its needs on top of the existing coding, but it is much uglier and bug-prone than doing it on this new code. Additional optimization can be applied on top of this, if need be.
